Wear-resistant cladding layer for guide sliding shoe of coal mining machine and preparation method of wear-resistant cladding layer

The invention discloses a wear-resistant cladding layer for a guide sliding shoe of a coal mining machine and a preparation method of the wear-resistant cladding layer, the wear-resistant cladding layer is prepared on the surface of the guide sliding shoe in an electric arc additive manufacturing mode, and used additive wires comprise, by mass, 0.05%-0.2% of C, 0.6%-1.5% of Si, 13%-20% of Mn, 6%-8% of Cr and 0 lt; blt; 0.1%, and the balance being Fe. The preparation method of the wear-resistant cladding layer comprises the following steps: (1) weighing raw materials of carbon, silicon, manganese, chromium, boron and iron powder according to the element mass ratio, mixing, and preparing the uniformly mixed powder into an additive wire through a wire forming machine; and (2) the surface of the pretreated guide sliding shoe is subjected to cladding through MAG electric arc additive manufacturing, and a wear-resistant cladding layer is obtained. According to the method, the wear-resistant cladding layer can be pr
