Taguchi optimization of hardness and scratch adhesion strength of multilayer Ti/TiN coatings on Ti-51 at%Ni alloy deposited via magnetron sputtering technique.

The near equiatomic Ti-51at %Ni alloy has excellent corrosion resistance, strength, shape memory and pseudo-elastic behaviour. However, it is lacking biocompatibility due to the release of hazardous Ni-ions when used as an implant. Thus, this research proposes optimizing the fabrication of multilaye...
