APDL and CEL languages were applied to compile the inner analytical programs, and the combination of VB, ANSYS Mechanical with ANSYS CFX was perfectly realized. Through the numerical simulation of magnetic-fluid lubricating film, the load-carrying performances of oil-film bearing with magnetic-fluid lubrication were analyzed, and the relationship among magnetic field intensity with oil-film pressure and temperature was quantitatively calculated. The numerical results have shown that the magnetic-fluid lubrication has obvious influences on oil-film pressure when magnetic field was applied on oil-film bearing, the lubricating viscosity increases with the magnetic-fluid intensity, and the oil-film pressure and temperature also increase with magnetic-field intensity. However, the increasing increment of oil-film temperature is far lower than that of oil-film pressure. The above conclusions prove that magnetic fluid with proper magnetic field can effectively improve the load-carrying capacity of lubricating oil film and enhances the stability of oil-film pressure. Moreover, the adjustable intelligent oil-film pressure with magnetic field is deduced to be feasible.

In order to reduce the postoperative inflammation by the slow release of drugs at the beginning of implanting, drug-loaded apatite coatings and chitosan-apatite composite coatings on the NiTi alloy surface were prepared in the Simulated Body Fluid concentrated by five (5×SBF) under constant bubbling of carbon dioxide gas by biomimetic synthesis method. The composition and surface morphology of the coatings were studied using scanning electron microscopy (SEM) and X-ray diffraction (XRD). Additionally, a bacterial inhibition test was conducted for evaluating the drug slow release effects from the drug-loaded coatings. The results indicated that the porous apatite coatings with the flake structure could be deposited using the 5 times Simulated Body Fluid, and the drug-loaded chitosan-apatite composite coatings with better drug slow release effect were obtained. The incorporation of chitosan into the coatings could effectively control the drug release rate and was favorable for achieving better drug slow release effects.

As a floppy alloy, the silicon steel with a content of Si of 6.5% has been paid much attention due to its maximum magnetic induction and minimum iron loss. However, the manufacture has been limited largely by conventional technics. By comparison, the silicon steel with a lower silicon content of 0.1%-4.0%, which was manufactured by conventional technics, also has a limited application. In this work, Molten Salts Electrodeposition has been employed to produce Fe-Si alloy. Technological parameters including influence of Molten Salts Electrodeposition technic in aggradation layer appearance and distribution of silicon content along with thickness. The results also show that the size of superficial particles on deposit layer increased gradually, the thickness of deposit layer was proportional to the current density on the deposit layer of Fe-Si.

Published: June 2013

Nitinol is metal alloy of nickel and titanium. It has wide range of applications. The most significant application is production of self-expanding stent-grafts, which are commonly used in vascular surgery. Stent-graft manufactures are confronted with two basic requirements: stents must have an infinite life; stents must be made of the thinnest wires us possible. Stent-graft failure or device fatigue remains major concern for stent-graft manufactures and researches. The stent-grafts are mechanically loaded, and also the device is placed in very aggressive environment. The corrosion stability of Nitinol is strongly dependent on the surface preparation: grinding, polishing, chemical etching. The paper deals with fatigue degradation of stent-grafts in corrosive environment.
