The changes of the microstructure and the mechanical properties of FeCrMoCBY amorphous coatings prepared by plasma spraying after heat treatment were investigated. 300, 400, 500 and 600 ℃ were selected as the heat treatment temperature, and the crystallization phenomenon occurred after the heat treatment at 600 ℃. The crystallization products of the coating heat-treated at 600 ℃ were a-Fe and Fe23(C, B)6. Heat treatment was beneficial to the microhardness and the bonding strength of the coatings. The microhardness of the coating heat-treated at 600 ℃ increased obviously, and the strongest bonding strength occurred in the coating heat-treated at 500 ℃. The improvement of the wear resistance of the coatings could attribute to heat treatment as well, and the wear resistance of the coating heat-treated at 600 ℃ was the optimum, compared with the coating heat-treated at 500 ℃.
