Possibility of estimation of mechanical stresses in nickel by the magnetic ponderomotive method
Authors: Kutepov A. Yu. , Kren A. P. , Gnutenko E. V. 
Published: July 2022

The paper considers a technique for assessing mechanical stresses in coatings by the magnetic ponderomotive method, based on the use of the magnitude of the magnet breakaway force and its relation to the magnetic characteristics of nickel (magnetic susceptibility), which change under the action of internal stresses. It is shown that the existing mechanical stress measuring equipment using X-ray, magnetic or ultrasonic methods have specimen size limitations or have low measurement locality. At the same time, a magnetic ponderomotive method for controlling mechanical stresses is presented, which does not have the indicated disadvantages. The change in the magnetic breakaway force on the thickness, applied and residual stresses caused by elastic and plastic deformations in the sample is theoretically substantiated. It is shown that the presence of residual stresses in the sample changes the nature of the dependence of the magnet breakaway force on the applied stresses. A calculation algorithm has been developed that allows measuring the magnet breakaway force to obtain the ratio between the applied and residual stresses. It is shown that the ratio between residual and applied stresses can be used to assess the degree of proximity to the critical stresses levels that lead to failure. Calibration surfaces are constructed for the dependence of applied stresses on magnetic separation force and thickness, corresponding to elastic-plastic deformation, as well as leveled calibration surfaces, corresponding to elastic deformation in the presence of residual stresses in the material. Experiments have been carried out on real samples and coatings, that determine the degree of approximation of internal stresses in the material to critical levels that may lead to destruction. It is shown that when comparing the readings of calibrated gauges with a certified tool, the largest deviation occurs at low stress values due to the inverse dependence of the breakaway force on the stress level.

Published: July 2022

Fasciolosis is one of the important diseases of livestock and has zoonotic importance. Fasciolosis can cause huge economic losses due to decrease in milk and meat production, decreased feed conversion ratio, and cost of treatment. Treatment and prophylaxis strategies for Fasciola infection are formed based on epidemiological data. The control of Fasciola infection can be attained by treating the animals with active anthelmintics. The use of different combinations of anthelmintics with a possible rotation is more effective against immature as well as adult flukes. Control of the intermediate host (snail) is vital for the reduction of fasciolosis. Due to the rapid growth of snails, the eradication is quite difficult in waterlogged and marshy areas. The use of different grazing methods and treatment of grazing areas can also help to control fasciolosis. A variety of antigens generated by Fasciola spp. have been shown to protect against liver fluke infection. The crude antigens, excretory/secretory, and refined antigens and their combination can be used as prophylactic treatment for the control of fasciolosis. The use of any of the single or combination of these methods can be very effective for the control of fasciolosis.

Published: July 2022

Abstract
The Ni-based single crystal superalloy has an excellent performance derive for high temperature fatigue strength. So, the expansion of application has been expected mainly in advanced gas turbine parts. However, it is known that the γ′ microstructure changes inside the material by plastic strain processing and heat-treatment. As a result, the fatigue strength was remarkably reduced. The new phenomenon was found that the B containing alloy coatings formed by thermal spraying restore high temperature fatigue strength of the weakened single crystal superalloy. We introduce the improvement effect of high temperature fatigue strength achieved by means of spraying the B containing alloy to CMSX-4 Ni base alloy substrate produced alterated layer.

Abstract
In this paper the point of view for the industrial coating manufacturing is presented. The perspective for industrial manufacturing of thermal spray coatings and facts that effect on the processibility of coatings in real life is often requested but seldom published. The perspective is from Pikoteknik Oy, which has a wide and long-term experience in the improvement and repair of machine parts in-situ, containing measurements, machining, coating and balancing of rolls and cylinders. Pikoteknik Oy is able to perform maintenance of paper cylinders on-site including pretreatments, thermal spraying and balancing quickly and skillfully. Due to their versatile state-of-the-art equipment, they are able to work flexibly on-site. To be able to operate on-site there are special demands for equipment, personnel and scheduling. The quality of the final product is in the hands of operator. Destructive testing is not possible to carry out and large amount of variables, such as moisture and positioning of equipment's exist. Grinding and grit blasting must carry out without dust formation due to the surrounding bearings and sensors. Large amount of experience and special knowledge is needed to be able to produce high quality coatings over paper cylinders.

Published: July 2022

Abstract
Industry faces the continual challenges of operating in less space and accelerating line speed in order to increase productivity, improve quality, and reduce cost. These challenges are particularly evident in the film and papermaking markets. To maintain competitive products in the market place, it is essential to incorporate rollers that are; lightweight, high stiffness, and compact. To satisfy these requirements, rolls made of carbon fiber reinforced plastics (hereinafter referred to CFRP) have proven effective and have come into wide use in many industrial fields. CFRP rolls are the structural materials that were developed mainly to improve the Young's modulus of rolls. Guiding and transfer rollers frequently require surface features such as non-adhesion and wear resistance. The typical surface treatments to CFRP currently employed are; painting, plating, and rubber lining or the like, but these treatments have their limits in the manufacturing process and effectiveness. Consequently, we have developed the technology to provide rolls with the desired surface by spraying various metals, ceramics, or cermets, directly on CFRP substrate. These sprayed rolls have been intensely monitored in actual operations to insure high speed capability and longevity. In this presentation, we will talk about the rotary bending fatigue test of CFRP rolls on which the carbide cermet was plasma-sprayed and the quality stability of the roll with the two-layer composites that was confirmed based on the test results.
The Microstructure Behavior of Thermal Sprayed TiO2 Coating on the Biodegradable Plastic

Published: July 2022

Abstract
The photocatalytic TiO2 coatings on bio-degradable plastic(polybutylene succinate:PBS) were prepared by HVOF and plasma spraying techniques using three kinds of agglomerated powders (P200: 200nm, P30: 30nm, P7: 7nm). The microstructures of coatings were characterized with SEM and XRD analysis, and the photocatalytic efficiency of coatings was evaluated through the photo degradation of gaseous acetaldehyde. Furthermore, for the estimation of the mechanical characteristics, wear resistance of coatings was estimated by weight loss obtained from the abrasion wear test. The results indicated that with respect to both the HVOF sprayed P200 and P30 coatings, the high anatase ratio of 100% can be achieved regardless of fuel gas pressure. On the other hand, the HVOF sprayed P7 coating exhibited largely decreased anatase ratio (from 100% to 49.1%) with increasing the fuel gas pressure, which may be attributed to the much higher susceptibility to heat of 7nm agglomerated powder. In terms of photocatalytic efficiency, HVOF sprayed P200 and P30 coatings seem to predominate as compared to that of plasma sprayed P200 coatings owing to the higher anatase ratio. However, the HVOF sprayed P7 coatings didn’t show the photo catalytic activity, which may result from the extremely small reaction surface area to the photo-catalytic activity and low anatase ratio. In addition, it was found that the thermal sprayed TiO2 coatings improve the wear resistance of PBS. Therefore, in the present study, possibility of production of further functional PBS plastic with photocatalytic performance and wear resistance by spraying of ceramics such as TiO2, was found.
Sealing of Thermally Sprayed HVOF Coatings for Boiler Applications

Published: July 2022

Abstract
Use of high-chlorine and alkali containing fuels such as biomass and refuse is increasing in production of heat and electricity. Fluidized bed boilers experience severe and harsh conditions, in which high temperatures combined with inhomogenous fuel cause severe material wastage to metallic parts in boilers. Thermally sprayed coatings have been reported to provide protection to the boiler tubes. However, thermally sprayed coatings have encountered serious problems, when corrosion has proceeded to the substrate material through voids and oxides in lamella boundaries. Sealing of the coatings can solve these problems. Sealing of coatings with commercial sealants and laser fusion treatment was investigated. Thermally sprayed HVOF metallic coatings were sealed with different commercial sealing agents and diode laser. The coatings were tested in molten salt, simulating condition of fluidized bed boiler superheaters. Optical microscopy (OM), scanning electron microscopy (SEM) and energy dispersive X-ray analysator (EDX) were used for examination of the tested and non-tested specimens. Some of the tested sealants protected the coatings adequately in the short time alkali chloride - alkali sulphate exposure test. Best sealant contained aluminium oxide and aluminium phosphate. Laser treated coatings had good corrosion resistance in a short-term test.

Abstract
Nanostructured and conventional hydroxyapatite (HA) feedstocks were evaluated to determine the effects of feedstock structure on the processing, properties and performance of coatings produced by atmospheric plasma spraying. The structure of the feedstocks was characterized using scanning electron microscopy (SEM). It was found that the nanostructured feedstock particles were formed by an agglomeration of nanostructured fibers having dimensions of less than 500 nm in length and below 100 nm in width. The average particle temperatures and velocities were measured during plasma spraying and found to be ~2650°C and ~315 m/s for the both feedstocks. The mechanical, microstructural and biocompatibility characteristics of coatings deposited on Ti-6Al-4V substrates were evaluated. The hardness was measured using Vickers indentation. The bond strength was determined via a tensile adhesion test. Microstructural characteristics of the coatings and their porosity levels were evaluated using SEM and image analysis. Phase analysis was carried out via X-ray diffraction (XRD) and aided by energy-dispersive X-ray analysis (EDS). The in-vitro behavior of these coatings was investigated in a simulated physiological solution in an attempt to simulate the environment of an implant in the human body.

Published: July 2022

Abstract
TiO2 coatings were prepared on polybutylene succinate (PBS) plastic by plasma spraying and High Velocity Oxygen Fuel (HVOF) spraying using agglomerated sub-micron TiO2 powder (200nm). Since PBS is well known material as bio-degradable plastic, the photo-catalytic TiO2/bio-degradable PBS composite material will exhibit purification of air and water without environmental damage. It was found that TiO2 agglomerated powders could be injected into PBS surface and anatase ratio greater than 60% could be achieved by 1pass plasma spraying. The anatase phase ratio decreased gradually with increasing pass count. By finding out adequate plasma spraying condition as a result of many experiments, TiO2/PBS composite material could be formed without large damage of PBS substrate. HVOF spraying could also provide TiO2 coating of 100% anatase ratio on PBS for 1~6 pass spraying. This means that 200nm agglomerated powders showed lower susceptibility to heat effect from gas flame and provided higher photo-catalytic activity as compared to plasma sprayed coatings. These coatings showed photo-catalytic degradation of 100ppm gaseous acetaldehyde (CH3CHO). As a result of photo-catalytic experiments, TiO2 coating formed by HVOF spraying showed a higher degradation rate because of higher anatase ratio. It means that 100ppm gaseous acetaldehyde was decomposed to less than 5 ppm after 7.2ks. Thermal spraying on PBS plastic in this investigation could imply both new application of thermal spraying and new possibilities of surface modification of low-melting point plastic.

Published: July 2022

Abstract
Spray coatings composed of zirconia, zirconium boride, and zirconium boroxide were reactively produced by Electrothermally-Exploded-Powder-Spray (ELTEPS) technique by using a mixed powder of zirconium and boron oxide particles. Substrates used were mild steels on which a Ni-20%Cr coating was plasma-sprayed as an undercoat for such a composite coating. Energy-controlled multiple sprays brought the hetero-structure of a top layer of Zr-O-B ceramic composite and a graded layer which composition continuously changed from the ceramics to the metal under-coat. The microstructure of the top ceramic layer was composed of Zr-O-B ceramic particles the size of which was on the order of several nanometers to a few hundred nanometers.

Published: July 2022

Abstract
Optical selective surfaces, i.e., surfaces with optical properties varying according to the frequency of the impinging radiation, have been exploited in several technical fields. These surfaces consist generally of doped semiconducting films, such as mixed oxides of Indium and Tin as well as Aluminium and Zinc. Thay are currently obtained by physical vapour deposition or sol-gel techniques. The present work aimed at demonstrating that coatings retaining optical selectivity can be obtained also by plasma spraying. Powders of Indium Tin Oxide (ITO) were prepared by an agglomeration technique and sprayed with a plasma torch under air and inert gas atmospheres. Both powders and coatings were characterised by X-ray diffraction, scanning electron microscopy and energy dispersive spectroscopy. Optical reflection coefficients of the coatings were determined in the wavelength range 0.3-20 µm, i.e., in the visible and in the infrared regions of the spectrum. The experimental results indicated that it was possible to deposit, by plasma spraying, coatings possessing optically selective properties.
