Abstract:Coating method was applied in cast-infiltration to form a layer containing boron, chromium and carbon with high hardness on the pan of scraper conveyor. By changing the percentage of alloy powders, the influence of different coatings on the microstructure and properties of the cast-infiltrated layer were studied. Experimental results show that the cast-infiltrated layer is mainly composed of Fe-Cr, Fe_(23) (C, B)_6, Cr_(23)C_6, martensite and ledeburite, the vickers hardness reaches the highest value of 800 HV, which is responsible for increasing nearly three times of the vickers hardness of the surface of scraper conveyor pan, the thickness of cast-infiltrated layer about 8 mm,and the vickers hardness declined gradually with increasing the B content.
