摘　　要：根据锅炉热管磨损部位及运行工况,开发相应的陶瓷-镍铬合金复合材料,采用激光熔覆加工技术,通过激光器产生的高能量激光,将高熔点、高硬度的陶瓷-镍铬合金复合材料与热管基体表面同时熔化并快速凝固,形成具有冶金结合的激光熔覆耐磨层。According to the wear position and operation condition of boiler heat pipe,the corresponding ceramic-nickel-chromium alloy composite material is developed.The high energy laser produced by laser is used to melt and solidify the ceramic-nickel-chromium alloy composite material with the heat pipe matrix surface at the same time to form the laser cladding wear-resistant layer with metallurgical bonding.
