description The friction and wear properties of laser cladding iron-base alloy by heat treatment were investigated in order to improve the durability of scraper conveyors by the wear test of the mechanical properties test. It mainly includes microstructure observation, hardness test, wear rate and appearance. The results show the crystalline grains of the heat treatment scheme are smaller, austenite and lath martensite grains can be observed clearly, which are helpful in improving the hardness. Meanwhile, gravimetric wear loss and friction coefficient are reduced. The wear situation of the heat treatment generates smooth surfaces, which can better prove their wear resistance is better.
