Abstract Shape memory alloys (SMAs) are widely used in biomedical engineering, including cardiovascular stents, artificial skeletons, and orthodontic implants. For the above applications, body fluids corrosion processes will inevitably cause deterioration mechanical properties of SMAs actuator during its service life, which threaten safety human health. To analyze such problems, experimental measurements have been carried out to investigate influence fluid on SMAs. Changes properties, as...
Abstract Interparticle bonding is considered the most important factor in cold sprayed coatings, determining mechanical properties as well physical and chemical behaviors. In this study, a Cu feedstock with low oxygen content deposited relatively high spray pressure temperature order to improve interparticle obtain coating cohesive strength. Mechanical between particles deduced from fracture morphology deformation behavior of simulated by finite element analysis.
Abstract This study demonstrates a novel method for improving the corrosion resistance of cold sprayed Al6061 coatings. Large stainless steel particles were added to commercial powder and mixture was deposited on Mg alloy AZ31B substrates using nitrogen gas at low working pressure temperature. It is shown that had shot-peening effect, thus increasing density as well SEM examination showed no incorporated in coating.
Abstract cBN/NiCrAl nanocomposite coating was deposited by cold spraying using mechanically alloyed composite powders. To examine the thermal stability of microstructure, annealed at different temperatures from 750 to 1000°C. The microstructure coatings characterized X-ray diffraction, scanning electron microscopy and transmission microscopy. results showed that nanostructure retained in when annealing temperature lower than 825°C which is 0.7 times melting point NiCrAl matrix. dislocation...
Abstract C-BNp/NiCrAl composite coating was deposited by cold spraying using a mechanically alloyed powder. To modify microstructure, especially the bonding at interfaces between c-BN particles and NiCrAl alloy matrix, sprayed particle/particle interface, annealing treatment series of temperatures in Ar atmosphere carried out. The results show that zigzag interface layer is formed particle matrix after 825°C for 300 min through reaction with NiCrAl. It also observed thickness increases...
