Structure and tribological properties of post-sputtered annealing nickel titanium alloy coatings onto 316l stainless steel.

The purpose of this study is to investigate the effect of the post-sputtering annealing process on the structure and tribological properties of the NiTi shape memory alloy (SMA) coatings. The NiTi SMA coatings were deposited onto the 316L stainless steel substrates using the sputtering PVD technique...
