The wear resistance of laser cladding iron-based alloy experiment has been carried out by the friction and wear experiment and a number of tests. Heat treatment of weld was further studied through microstructure observation, hardness test, the quality of wear and wear appearance. The results show that the crystalline grains of the heat treatment scheme are homogeneous and smaller. Meanwhile, the wear quality and friction coefficient are reduced and the wear morphology is improved. The wear situation of the non-heat treatment scheme revealed corrugated folds, tearing and adhesive bumps occurring in along friction surfaces whereas that of the heat treatment generated smooth surfaces and also confirms shallow fold and peeling along friction direction revealing the most preferred scheme.
