Paper Abstract

To prevent the surface of coat tools from eroding and improve the longevity of coat tools, the laser-heating and fuse-permeating process, a method which adopt high-power acute laser scan for W18Cr4V steel and for micron spraying WC tools to acquire the alloy-coating, get fusing or nonfusing of tools further surface, however, a fuse- permeating layer is formed between the further surface and original body, then quickly-cooled to concord with some property. According to the experiment of laser-phased harden layer atom distribution. Atom W has the obvious diffusing tendency to the original body, the thickness of the fuse- permeating layer >= 20 micrometers , and the crystal particle is small. All this get high performance to decrease the fracture which extend along crystal side.
