摘要

TiNi alloy (nickel–titanium shape memory alloy) exhibits extensive applications in medical and mechanical fields owing to its superelasticity and wear resistance. However, as a wear-resistant material, it suffers from inherent limitations including high friction coefficients, and severe adhesive wear. Doping with Cu can significantly optimize its tribological performance through mechanisms involving phase transformation behavior modulation, wear mechanism refinement, and surface modification enhancement. In this work, the optimization of wear resistance of TiNiCu alloy was achieved by replacing Ni with Cu. The Ti48.5Ni41.5Cu10 alloy thereby demonstrates exceptional wear resistance, attributable to its low-hysteresis and high-recoverability superelasticity. This study substantially expands the application potential of TiNi-based alloys.
