Plasma arc was used as a heat source to make a surface quenching on alloy cast iron, and orthogonal test was used to optimize the surface hardening technological parameter of plasma arc. The influence of the technological parameters on hardness and depth of the hardening layer was analyzed, and the microhardness and the microscopic structure condition after being disposed were also analyzed and discussed.
