针对井下立柱、千斤顶易腐蚀的现状,将液压支架上的立柱、千斤顶的易腐蚀和易磨损的部位进行激光强化处理,即应用激光熔覆技术在立柱、千斤顶的表面熔覆一层不锈钢,这不仅改变了立柱、千斤顶表面耐磨层的组织结构和化学成分,大大提高了其表面的耐腐蚀和耐磨性能。工业性试验和实际应用对比表明,激光强化不锈钢立柱的使用寿命是普通镀铬立柱使用寿命的6～8倍,比目前包覆不锈钢提高了2～3倍。
For underground columns, jacking corrosion status, the hydraulic support column, easy to corrode and easy to wear parts of the laser-intensive processing, that is, laser cladding technology in the column, the surface of the jackets cladding a layer of stainless steel, which Not only changed the column, jack surface wear layer structure and chemical composition, greatly improving its surface corrosion resistance and wear resistance. Comparison of industrial tests and practical applications show that the service life of laser-strengthened stainless steel columns is 6 to 8 times of the service life of ordinary chrome-plated columns, which is 2 to 3 times higher than the current coated stainless steel.
