摘　　要：为了对液压支架进行表面激光熔覆应用研究,以液压支架用27SiMn钢试样为基体,激光熔覆Ni60合金粉末,对熔覆层分析研究。综合结果表明,成形的熔覆层质量满足要求,具有很高的显微硬度和较强的耐腐蚀性能,能达到实用要求。此研究结果为激光熔覆在液压支架上的应用奠定了基础,提供了一种对液压支架进行表面处理新的可行性工艺方案。In order to study the application of laser cladding in hydraulic supports,takes the sample-the hydraulic supports which was made of 27SiMn steel-as the matrixbase,and analyzes the cladding layer which was claded with Ni60 alloy powder using laser.Synthesis results show that,the forming cladding layer meets the requirements in quality,and has high hardness and strong corrosion resistance,moreover it can achieve the practical requirement.Results of this study establish the basis of the application of laser cladding in hydraulic supports,and provide a new process scheme for the surface treatment in hydraulic supports.
