激光熔覆Ni基WC涂层内铸造WC颗粒溶解特征的研究
Investigation on Dissolution Characteristics of Cast WC Particles in Ni-based WC Coating by Laser Cladding
摘要
Abstract
WC particles reinforced Ni-based coating is produced by laser cladding on the surface of Q235 steel. The dissolution characteristics of cast WC particles are investigated. The results show that the cast WC particles are dissolved almost completely in the bottom of coating, and interact with Fe from the substrate to precipitate the herringbone M6C carbides. In the center of coating, the cast WC particles are dissolved and the carbides such as M7C3, M12C and M23C6 are precipitated. At the edge of coating, most of cast WC particles are dissolved partially to form an alloyed layer identified as M6C, resulting in the preservation of polygonal and high hardness characteristics.关键词
