Abstract

Ni60 coating provides excellent hardness and wear resistance, it is usually used to strengthen the parts worked the severely conditions with intensified friction. While Ni60 has a strong crack susceptibility due to its high brittleness and high thermal gradient in transient cladding process. In order to improve the wear resistance of Ni60 coating, the strong carbide forming element is introduced. Among those elements, Tantalum (Ta) is a typical element, it exhibits an excellent chemical inertness, which is an important property in laser cladding. The wear behaviors of Ni60+Ta.wt% composite coating are studied. The results show that Ta improves the toughness of Ni60 composite coating and sliding and abrasive wear resistance while decrease the crack susceptibility.
