Mechanical Properties of Plasma Cladding on Coal Mining Machine Guide Shoe
Due to the harsh environment of coal mining,the slide shoe,as a guiding and supporting part of coal mining machine,often fails.Plasma cladding technology has the advantages of high energy density,high temperature of plasma arc column and strong cladding bonding force,which is regarded as a more advanced surface treatment and remanufacturing technology.By applying the plasma cladding technology to the guiding boots of coal mining machine and studying their mechanical properties,it is found that their hardness is greatly improved,which is favourable for underground use.
