چکیده
Solution precursor plasma spray (SPPS) can prepare thermal barrier coatings (TBCs) with nanostructures, which modify the adhesion and wettability of molten silicate environmental deposits (CMAS) on surface TBCs, thereby improving resistance TBCs to CMAS corrosion. In this study, SPPS layers micro-nano double scale structures were prepared conventional atmospheric spraying (APS) coatings. The effect process parameters wetting infiltration behavior investigated. results show that micron structure is more sensitive parameters. Lower viscosity, closer distance, smoother APS layer are favorable form typical dense structures. After covering layer, diameter reduced by about 40% steady-state contact angle increased up three times. reason effectively trap air an between coating CMAS. addition, nano-particles play a important role in formation turn determines properties. While influence time needed reach steady state. However, composed have very loose weak cohesion, they degrade fail rapidly after Therefore, maintaining excellent while taking into account their lifetime reliability has become focus further research.

Micro- and Nano-scale Tribo-Corrosion of Cast CoCrMo
Previous studies have established that some of the wear damage seen on cast CoCrMo joint surface is caused by entrained third-body hard particles. In this study, wet-cell micro-indentation and nano-scratch tests have been carried out with the direct aim of simulating wear damage induced by single abrasive particles entrained between the surfaces of cast CoCrMo hip implants. In situ electrochemi...
