本文通过磨损实验、腐蚀实验以及小能量冲击剥落试验，证实了经盐浴复合处理的工件抗蚀耐磨性及抗冲击剥落能力均高于镀硬铬及镀锌磷化涂二硫化铂。同时，盐浴复合处理的总费用较低，在煤矿机件上具有广泛的应用前景。 In this paper, abrasion test, corrosion test and small energy impact peel test were carried out to confirm that the corrosion resistance and abrasion resistance and impact resistance of the workpiece treated with salt bath were all higher than those of hard chrome plating and zinc phosphating coated platinum sulfide. At the same time, salt bath complex treatment of the total cost is low, in coal mining machinery has a wide range of applications.
