Property of laser cladded Ni60A＋20%WC alloy of cylinder of single hydraulic support
Abstract：Combining with the characteristics of the special environmental conditions in mining, taked the sample-the hydraulic support which was made of 27SiMn steel used in coal mines as the matrixbase, and analyzed the cladding layer which was cladded with Ni60A＋20% WC alloy powder using laser. Microstructure and properties of the cladding layers were examined by means of SEM, hardness test, wear testand salt-mist test. The results show that metallurgy binding interface between the cladding layer and the base metal is obtained. Wear-resistance and hardness of the clad 27SiMn steel are obviously improved. The cladding layer has high hardness and strong corrosion resistance.
