| Abstract: | In this paper, the writer reseached the technology parameter of W18Cr4V steel laser surface quenching. the results of testing show that the quenching layer of no melt on the face can be gained when the technology parameter d is equal to 1.5mm,q is equal to 124W/mm2,v is equal to 18mm/s and the heating temperature is between Acl and Tmelt. The depth of quenching layer is equal to 0.25mm and its micro-hardness HV0. 1 is between 950 and 1050 and its microstruture is composed by M+Cem+A'. |
