| Abstract: | TiNi alloy is an excellent tribo-material compared to conventional wear-resistant materials, which is closely related to its superelasticity originating from stress-induced matensite transformation, along with rapid strain-hardening, erosion-resistance and fatigue-resistance. From the points of mechanism, conditions as well as influence factors of superelasticity, the contributions to superior tribological performance of TiNi alloy were discussed. The measures to enhance the superelasticity and to fully exert it were summarized. The current situation of tribological applications of TiNi alloy was reviewed and research tendencies were put forward. |
