| Abstract: | The ceramic coating was obtained by micro arc oxidation(MAO) on NiTi shape memory alloy(SMA) substrate.The NiTi SMA samples were pre-treated by dealloying immersed in aqua regia at room temperature.The surface morphology of the treated specimens,the composition and the MAO manufacturability of the ceramic coatings were investigated.And the surface morphology of the treated specimens was compaired with which of the commercially pure titanium and the uneroded NiTi SMA samples.The results show that the manufacturability and the surface morphology of the samples pre-treated by aqua regia for 10min at room temperature is closest to that of the commerciallly pure titanium at the same MAO experiment conditions.The phase composition of the ceramic coatings is mainly NiTi phase and anatase phase.And it is generally consistent for the MAO samples before and after pre-treatment by aqua regia.The content of the anatase phase increases gradually with the extension of the dealloying time of aqua regia. |
