Study on Laser Cladding Repair of Flat Chain of Scraper Conveyor
With a flat chain with the wear failure as the research object, the experiment of laser cladding for the matrix is carried out by using the Fe-based alloy powder. The metallographic structure, micro-hardness and wear resistance under different cladding process parameters are analyzed. The parameters with a laser power of 1600 W, a scanning speed of 600 mm·min -1, a feeding rate of 4.0 rad·min -1 and a cladding layer number of 3 are the optimal process parameter set. Under this parameter set, the cladding layer has a good metallurgical bonding with its matrix , has no pores and other flaws, and has the hardness and wear resistance which are better than those of the matrix.
