摘　　要：针对矿井井筒提升罐道存在严重的磨损与腐蚀问题,提出先在轨道表面喷焊F102B合金,然后采用电弧喷涂铝工艺对其它表面进行防腐。试验结果表明硬度、耐磨性都有提高,耐蚀性也有所增强;电弧喷涂铝防护性能优异,且不至影响F102B合金层的性能。For the abrasion and corrosion occurred on the hoist guide in the mine shaft, the paper provided to spray and weld F102B alloy on the guide and then to have a electric arc aluminum painting technology on the surface of the guide to control corrosion The test results showed that the hardness and abrasion resistance of the alloy are 25 times higher and 23 times higher individually The corrosion resistance of the alloy could be improved The protection performances of the electric arc aluminum painting are excellent and would not affect to the performances of F102B alloy coating
