Abstract

Mold failure usually starts from the surface. The mold life expectancy can be effectively extended by improving the surface properties and performance of the mold. Laser cladding technology is a new type of materials processing and surface modification technology. Because the advantages of cladding surface abrasion resistance, corrosion resistance, anti-oxidation and base metal metallurgy combination, so widely used. In this paper, 45 steel surfaces are treated by laser cladding using the LWS-500 laser welding. The cladding material is nickel-based alloy powder TiC ceramic particles. Through the observation of microstructure of the cladding layer and measuring the micro-hardness, it analyzes the influence of Ni/TiC ratio on the cladding structure and microstructure hardness of the layer. Results show that the Ni60+20%TiC alloy powder for laser cladding can get the best quality of cladding layer. Deformation of the base metal is very small. It has a large number of applications in engineering practice currently. To improve the quality and the service life of the die has great economic benefit and social benefit.
