Abstract

DK460UF is deposited on the surface of 9341 high-speed steel by DZ-4000( ) multifunctional surface hardening machine which use argon as shielding gas. They occur metallurgical reaction by electro-spark deposition technology to make electro-spark deposition migrate to the surface of the tool and form high-performance deposition layer with a strong and stable binding force of matrix. Under the process parameters: 2min, 80V 3000Hz 150 F obtain the deposited layer which has no obvious defects such as micro-cracks and bubbles, thickness 89 m, microhardness 1487.5Hv. No clear boundaries exist in the deposited layer and the substrate. Transition zone thickness is greater than 20 m.
