不同表面粗糙度的冷轧板进行磷化处理后, 采用T1000粗糙度仪对基板表面粗糙度进行测定, 通过脱膜法、扫描电镜、摩擦试验机对磷化膜膜重、表面形貌、摩擦系数和耐磨性进行了研究。结果表明, 基板表面粗糙度对磷化膜膜重影响不大; 表面粗糙度较小, 则形成的磷化膜均匀致密且粒径较小, 磷化膜摩擦系数相对较大, 耐磨性相对较差; 反之若表面粗糙度较大, 则形成的磷化膜相对疏松粒径较大, 磷化膜表面摩擦系数较小, 耐磨性较好。

Cold-rolled steel sheets with different surface roughness were phosphatized. The surface roughness was tested by T1000 roughness tester, the weight of the phosphate coating was measured by removing the coating by chemical method. Scanning electron microscopy(SEM) and friction testing were used to characterize the performance of the phosphate coating, including the surface morphology, the friction coefficient and wear resistance. The results show that the substrate surface roughness has little effect on the weight of the phosphate coating. The smaller the surface roughness of the substrate is, the more uniform the phosphate coating is and the smaller the size of the particles is, however, the friction coefficient is relatively larger and the wear resistance is relatively poorer, and vice versa.
