摘要 针对液压支架立柱常用材料27SiMn钢,分别采用电镀铬、激光熔覆、包覆焊工艺进行表面处理,对涂层的微观组织、显微硬度、耐磨性和耐腐蚀性进行测试与比较,并参考了实际生产因素,对3种工艺的经济效益和环境友好性进行了对比分析。结果表明,电镀铬涂层表现出较高的硬度和耐磨性,但耐腐蚀性较差;激光熔覆涂层的硬度和耐磨性较低,但耐腐蚀性较好;包覆焊涂层硬度为498.9 HV,约为电镀铬涂层的0.74倍;磨损失重为0.03862 g,约为电镀铬涂层的1.34倍;腐蚀失重为0.00126 g,约为电镀铬涂层的0.12倍、激光熔覆涂层的0.75倍,包覆焊涂层在保持较高硬度和耐磨性的同时,也拥有优异的耐腐蚀性。此外,包覆焊工艺的生产成本极低,且无污染,具有长期社会效益、经济效益和环境效益。 27SiMn steel,which was commonly used for hydraulic support columns,was treated by chrome plating,laser cladding and cladding welding.The microstructure,microhardness,wear resistance and corrosion resistance of the coating were tested and compared.Considering the actual production factors,the economic benefits and environmental friendliness of the three processes were compared.The results show that the chrome plating coating exhibits high hardness and wear resistance,but its corrosion resistance is poor;the laser cladding coating has lower hardness and wear resistance,but its corrosion resistance is better;the hardness of the cladding coating is 498.9 HV,which is about 0.74 time than that of the electroplated chrome coating,the grinding loss is 0.03862 g,which is about 1.34 times than that of the electroplated chrome coating,the corrosion weight loss is 0.00126 g,which is about 0.12 time than that of the electroplated chrome coating,and0.75 time of the laser cladding.Cladding coating has excellent corrosion resistance while maintaining high hardness and wear resistance.In addition,the production cost of the cladding welding process is extremely low,pollution-free,and it has long-term economic and social benefits for the mining bracket industry.
