Laser strengthening manufacturing and remanufacturing technology can be used to repair the surfaces of mud pumps, coal mining machine gear shafts, rocker arms, gears, bushings, cylinders, guide sliders and picks. Laser strengthening of tunneling engine cylinders, brackets, bushings and cutting teeth; The surface of the hydraulic cylinder is laser-fused with stainless steel alloy. Laser repair of worn areas on the surface of the middle trough, transition trough, gearbox, gear shaft, spiral bevel gear and shaft parts of the scraper conveyor.

The technological innovation of laser additive manufacturing for slurry pumps lies in:

(1) Through laser additive manufacturing composite material technology and advanced composite material and structural technology, the additive manufacturing repair of the waste slurry pump is achieved, and its anti-wear performance reaches the wear resistance level of 60HRC of the new high-chromium cast steel.

(2) The slurry pump is made of common cast iron material to meet the requirements of rigidity and strength. The shape and size of the additive manufacturing wear-resistant ternary composite material (coating) are reserved to form a new type of slurry pump with wear-resistant ternary composite material covering common cast iron, and it reaches the wear resistance level of 60HRC of traditional high-chromium cast steel. It can be repeatedly prepared and recycled, and the entire process is energy-saving and environmentally friendly.
