摘要

Structure and mechanical properties of nanostructured Ti and Ti-Ni, Ti-Nb-Zr, Ti-Nb-Ta shape memory alloys, and TiCaPCON biocompatible coatings were characterized by metallographic analysis and instrumented indentation. Discussed is the mechanism of localized deformation of the coatings deposited onto nanostructured substrates. Deformation was found to proceed inhomogeneous, through formation of shear bands during penetration of a Vickers diamond indenter into TiCaPCON coatings on the substrates with high elastic modulus especially.
