Abstract The wear-proof layer of hard materials is an important component of the nuclear motor spindle. It has high requirements for material properties in wear resistance and corrosion resistance. Cobalt-based alloy Co-1, Co-2 (increased tungsten content) and nickel-based alloy Ni-1 were prepared by hot isostatic pressing process. The performance of the material was analyzed by disc-to-disc friction test and electrochemical corrosion test. The results show that the Co-based alloy Co-2 has a friction factor of 0.08 and a pitting potential of 0.55 V, which is more suitable as a wear-resistant layer material.
