【Abstract】 Fe base Cr - Ni - W - Nb system alloy powder is developed through high temperature hardness testing and high temperature abrasion experiment. The material possesses the properties of abrasion resistance at high temperature and is suitable to plasma arc spray- welding. Which can be the one instead of expensive Ni base and Co base powder. The effect of alloy element on abrasiveness at high temperature and abrasive mechanism are studied also.更多还原
