The wear characteristics were investigated experimentally in Ti-Ni base shape memory alloys, which have the superior thermomechanical properties and the high corrosion resistance. The sliding tests were performed at a constant sliding speed and a sliding distance. Specimens were Ti-50at%Ni and Ti-45at%Ni-5at%X (X : Ag, B, Fe, Nb, Pb) fabricated by a spark-plasma sintering method, and a Co-based alloy (Stellite 6) was used as a reference material. The effects of additional elements and hardness on wear were investigated in relation to the specific wear rate and hardness. Result show that Ti-Ni-Ag alloy has high wear resistance equivalent to a Co-based alloy.
