对表面涂层因素对锚片间摩擦特性的影响进行研究和分析,比较并分析了未加涂层、镍磷涂层和渗硫涂层的三组液压顶升设备锚片的摩擦特性数据。结果表明:基体的表面精度大于两组涂层的表面精度,镍磷涂层的表面粗糙度最大;经过表面涂层处理之后其表面硬度明显增强,且表面渗硫涂层厚度比表面镍磷涂层的厚度大;涂层因素对锚片工况的改善有明显的影响。此外,渗硫涂层比表面镍磷涂层对提高液压顶升设备锚片有更好的减摩特性。
The influence of the surface coating factors on the friction characteristics between the anchor sheets was studied and analyzed. The friction characteristics of the anchor sheets were compared and analyzed with three sets of hydraulic jacking equipment without coating, Ni-P coating and sulfurized coating. The results show that the surface precision of the substrate is larger than the surface precision of the two coatings, and the surface roughness of the nickel-phosphorus coating is the largest. The surface hardness of the nickel-phosphorus coating is obviously enhanced after the surface coating, The thickness of the layer is large; the coating factor has a significant effect on the improvement of the working condition of the anchor sheet. In addition, the sulfurized coating than the surface of nickel-phosphorus coating to improve the hydraulic lifting device anchor film has better anti-friction properties.
