Abstract:The preparation of a thin hard coating is the main challenge in the coating of NiTi articles. To achieve a thin coating of titanium nitride (TiN) on NiTi substrate, physical vapour deposition (PVD) was proposed in this study. Deposition of TiN coating was carried out at the nitrogen flows of 0.79 and 0.93 Pa. Phase composition, thickness, porosity, adhesion strength, hardness, and tribological properties of the TiN coatings were evaluated. The adhesion of the coating to the substrate was acceptable.
