The erosion and wear characteristics were investigated experimentally in Ti-Ni base shape memory alloys, which have the superior thermomechanical properties and the high corrosion resistance. The erosion tests were conducted by the method, which collides the compressed water of the high temperature and high pressure with the specimen. The erosion, which is caused by a combination of the cavitations and the shear stress due to the high-speed hot water flow, can be estimated by this method. Furthermore, the sliding tests were performed at a constant sliding speed and a sliding distance. Specimens were Ti-50at%Ni and Ti-45at%X(X : Ag, B, Nb, Pb) fabricated by a spark-plasma sintering method, and Co-based alloy (Stellite 6) was used as a reference material.
