【Abstract】 The layer heat treatment of HT200 was carried out with different parameters. Then, the mechanical properties were measured and the microstructure was analyzed. The results show that the hardness and wear resistance of the hardening layer are 4 times and 2 times those of the matrix, respectively.更多还原
