中文摘要: 为提升液压支架用油缸缸体等内孔部件的服役性能，集成大功率光纤激光器开发了内孔熔覆装备，进行了 27SiMn 缸体内壁熔覆工艺验证，并取样进行了显微结构、硬度、耐磨性能检测，结果表明:缸体内壁熔覆表面 平整无缺陷，熔覆层与基体呈冶金结合;熔覆层主要组织为马氏体;熔覆层硬度较基体略高，且耐磨性能约为基 体的 1.5 倍，既提升了缸体内壁的使用性能又便于缸体内壁熔覆层的机械加工。
Abstract:In order to improve the service performance of the inner hole parts such as the column cylinder of hydraulic support, the inner wall cladding equipment was developed with the integration of high-power fiber lasers, the cladding process on the inner wall in the 27SiMn cylinder was verified, and the microstructure, hardness, and wear resistance were tested. The results show that the inner wall cladding surface is flat and without defects, and the cladding layer is metallurgical combined with the matrix. The main structure of the cladding layer is martensite. The hardness of the cladding layer is slightly higher than that of the substrate, and the wear resistance is about 1.5 times that of the substrate, as a result, not only the performance of the inner wall of the cylinder was improved but also the machining properties of the cladding coating in a narrow space are optimized.
