| 摘 要： | To improve wear resistance of surface will increase the service life of gray cast iron directly.This paper presents that gray cast iron surface coated with alloy powder is locally remelted by TIG arc of increase the wear resistance.The influences of arc current and scanning rate etc on surface properties are found.Under different conditions.the microstructure,hardness and wear resistance of remelted layer are analyzed and measured.The results indicate that the gray cast iron surface can be strengthened by TIG arc local remelting treathent.Especially,surface alloying hardening effect is best and surface properties are improved remarkably.

| Abstract: | To improve wear resistance of surface will increase the service life of gray cast iron directly. This paper presents that gray cast iron surface coated with alloy powder is locally remelted by TIG arc to increase the wear resistance. The influences of arc current and scanning rate etc on surface properties are found. Under different conditions, the microstructure, hardness and wear resistance of remelted layer are analyzed and measured. The results indicate that the gray cast iron surface can be strengthened by TIG arc local remelting treatment. Especially, surface alloying hardening effect is best and surface properties are improved remarkably. |
