The formidable and multivariate coal-mining conditions during the production often lead to various improper damage and inactivation of guide foot. Wear is the most severe problem. We do the research on optimization design of the materials by plasma cladding technic to improve the wear resistance: The Cr28MnV ferrous alloy overlay was deposited on the surface of 45# tempered steel backing. The martensitic structure with high strength, high hardness, and high abradability evenly distributed alloy carbide can be gained after cooling the overlay. The combined backing has a good obdurability which can satisfy the requirement of coal mine complex conditions after modifying treatment.
