Published: August 2024

INTRODUCTION. The determination of nephrotoxicity markers is a useful and necessary step in the detection of renal injury in animal experiments; these markers help accurately localise organ damage. With multiple damaging agents, known nephrotoxicity mechanisms, and laboratory animal species, there is currently no widely accepted renal injury marker that meets all the prerequisites.AIM. This study aimed to collate literature data on nephrotoxicity markers, evaluate their prognostic significance, and formulate general recommendations for assessing urinary system function in preclinical studies.DISCUSSION. This article describes a comparative analysis of the nephrotoxicity markers recommended by regulatory authorities for monitoring drug-induced kidney injury. According to the results, the most commonly used and prognostically significant markers of acute kidney injury in preclinical studies are cystatin C, albumin, total protein, kidney injury molecule-1 (KIM-1), neutrophil gelatinase-associated lipocalin-2 (NGAL), and clusterin. Chronic kidney injury markers include the above, plus the glomerular filtration rate, creatinine, urea, and osteopontin. An electrolyte panel can be used for the differential diagnosis of pre-renal azotaemia and acute kidney injury. Potential limitations for the routine use of kidney injury markers in preclinical research include the high cost of their quantitative determination and the lack of information on the applicability of data obtained from different species of laboratory animals.CONCLUSIONS. Having compared the prognostic significance of common biomarkers, the authors provided general recommendations for a comprehensive preclinical assessment of urinary system function, including laboratory investigations, instrument-based tests, and necropsy. A preclinical study design should be based on the study aims, the species and number of animals used, and special considerations for the test article.

Cold Atmospheric Plasma Metallization of Power Semiconductor Devices with CuSn Pseudo-Alloys for Diffusion Soldering
Authors: Ockel Manuela , Gökçen Aleyna , Ottinger Bettina , Petersen Matthias , Voigt Christian , Franke Jörg 
Published: August 2024

Abstract
Cold atmospheric plasma spraying is used to produce thin coatings of copper and tin between 20-80 μm thickness for use in diffusion soldering. This study presents an alternative process to apply composite solders directly onto power electronic bare dies. The formation of intermetallic phases may be promoted by the homogeneous distribution of the Cu and Sn particles as they are presented not in a layered structure but as a pseudo alloy within the coating. The Cu and Sn powder is mixed in situ using two powder conveyors, enabling adjustable mix ratios. The presented approach has been shown to produce a homogeneous particle distribution within the coating. Furthermore, preliminary experiments indicate the feasibility of the technology for applications in diffusion soldering.
Subsurface Weave Pattern Influences on Cold Spray Deposits onto Woven Fiber Reinforced Composites
Authors: Kaminskyj Madison , Mennie Nicholas , Singh Nand , Koohbor Behrad , Haas Francis M. 
Published: August 2024

Abstract
The polymer cold spray (CS) process has been demonstrated as a promising coating and repair technique for fiber-reinforced polymer composites (FRPs). However, a noticeable variation in coating thickness (herein referred to as checkerboard pattern) often occurs in the initial (bond) layer of low-pressure CS deposition. The checkerboard pattern occurs due to essentially periodic variations in matrix thickness above the subsurface fiber weave pattern. When the bond layer exhibits the so-called checkerboard pattern, the CS deposition for subsequent layers may be negatively affected in terms of deposition efficiency, porosity, adhesion, surface roughness, and surface thickness consistency. The present work compares results of both numerical simulations and experimental studies performed to reveal the governing mechanisms for and elimination of checker-boarding. Numerical single particle impact simulations are conducted to observe various thermomechanical domains for CS impact on the FRP surface in different regions of the composite material. Complementary experimental CS studies of exemplar powders onto FRPs with various surface interlayer thicknesses are also presented. Experimental analyzes of deposits include microstructural observations to compare against the simulations while also providing practical strategies for the elimination of checkerboarding effects.
Numerical Simulation of the Shaft Parts Repairing Process by Laser Metal Deposition Technique

Published: August 2024

Abstract
Restoring the damaged shaft parts to extend their service life is an economical and environmentally friendly solution. In recent years, the laser metal deposition (LMD) process has received increasing attention in component restoration. However, the residual stress and deformation inevitably occur due to the heat input, leading to the deflection of the repaired shafts. Therefore, this study aims to minimize the deflection of LMD-repaired shaft parts through parameter optimization. The width and height of the LMD deposit as a function of the laser power and traverse speed were achieved by fitting a series of one-pass experimental results. Based on it, the finite element analysis was conducted to clarify the effect of the repairing conditions (e.g., laser power, traverse speed, and initial substrate temperature) on the deflection and residual stress distribution of the shaft parts after LMD repairing. A 304 stainless steel round bar with a diameter of 6 mm was served as the component to be repaired. The deposit was 316L stainless steel, whose deposition process was realized by the element birth and death technique. The results indicated that the free-end of the specimen experienced complicated deformation during the LMD and cooling process. After cooling off, the substrate presents a residual compressive stress along the axial direction. Moreover, the substrate deflection can be reduced by improving the initial substrate temperature. This study provided an important reference for optimizing the process parameters in repairing the shaft parts.

Published: August 2024

Abstract
The method of simulating the wear performance under working conditions using a high-temperature ultra-high-speed wear testing machine was adopted to study the effect of feed rate variation on the wear behavior and scraping performance of the AlSi/hBN sealing coating and TC4 simulated blades. The macro and micro morphology of the coating and blades were analyzed by stereomicroscope and scanning electron microscope (SEM). The phase composition of the coating was analyzed by energy dispersive spectrometer (EDS) and X-ray diffraction. The results showed that, under the conditions of temperature of 450°C, line velocity of 300m/s, and feed depth of 500μm, the change in feed rate significantly affected the macro and micro morphology and wear mechanism of the AlSi/hBN sealing coating-TC4 simulated blades. At low feed rates, severe wear occurred, mainly manifested as grooving, adhesion transfer, and overheating mechanisms. At medium to high feed rates, good machinability was observed, mainly manifested as cutting and transfer of coating material to the blades.
Enhanced Coating Deposition by Development of Oxide Shelled Aluminium Nitride

Published: August 2024

Abstract
The need for effective electrical insulation coupled with good thermal conductivity in power electronics has led to an exploration of suitable solutions for components like Insulated-Gate Bipolar Transistors (IGBTs). Considering its material properties, AlN emerges as a promising candidate for this application due to its high thermal conductivity, good electrical insulation and ample dielectric strength. However, aluminium nitride (AlN) has a low deposition efficiency when applied by atmospheric plasma spraying (APS). In contrast to AlN, alumina has a very good deposition efficiency during thermal spraying. Feedstock development was conducted to enhance the coating deposition for AlN. Therefore, a parameter study was carried out with AlN feedstock material to form a protective alumina shell around the AlN particles. Subsequently, the heat-treated powder was applied on an aluminium substrate by APS. X-ray diffraction (XRD) analysis displayed that, the heat-treated feedstock material contained AlN and α-Al2O3 phases. It was observed from scanning electron microscopy (SEM) analysis that the AlN particles formed an oxide shell which led to an enhanced deposition efficiency with a high amount of AlN in the coating. The coatings were also investigated by XRD and SEM to prove the presence of AlN and alumina. For the first time, oxide shelled AlN was successfully applied by thermal spraying with sufficient coating deposition and enhanced AlN-content in the coating.

Published: August 2024

Abstract
Due to their promising photocatalytic properties under visible light irradiation, thermally sprayed ZnO-TiO2 coatings are of interest as substitute for TiO2 for various industrial applications, like hydrogen production via water splitting or the reduction of organic pollutants in water. Suspension spraying is an effective method to produce coatings in the binary ZnO-TiO2 system to form Zn2TiO4 in-situ during the spraying process. Aqueous suspensions containing fine dispersed ZnO and TiO2 particles are mixed at tailored composition and sprayed using the SHVOF and SPS spraying processes. Coatings with homogeneous distribution of elements and different surface structures and phase compositions are obtained. The phase composition is analyzed via XRD. UV-Vis spectroscopy measurements and photocatalytic tests of Rhodamin B degradation are performed. The potential to use appropriate binary suspension feedstock to produce ZnO-TiO2-Zn2TiO4 coatings with different microstructures and photocatalytic properties is presented.
