氧化石墨烯含量对建筑用316L不锈钢表面Ni基涂层组织和摩擦学性能的影响 : = Effects of GO Contents on the Microstructure and Friction of Ni-Based Coatings on 316L Stainless Steel

为深入了解石墨烯对涂层组织结构与性能的影响,通过脉冲电沉积工艺在316L不锈钢表面制得石墨烯/Ni基复合涂层,通过试验测试手段对涂层的组织结构和摩擦学性能进行分析。结果表明:随石墨烯的加入量增大,在涂层表面形成了更多的微凸体并存在一定程度的团聚现象,使涂层表面粗糙度增大。随着复合镀液内石墨烯加入量的逐渐升高,复合镀层的厚度增加。各涂层都在45°、52°与76°处形成了衍射峰,此时镀层是由面心立方Ni构成。加入0.2 g/L与0.4 g/L石墨烯条件下得到的涂层摩擦系数比基体分别减小了3%与12%。磨损率随载荷的增大而上升,加入石墨烯的复合涂层磨损率相对基材均有所减小。加入0.4 g/L石墨烯制得的涂层形成了光滑磨损表面,磨痕深度也较浅,说明适量加入石墨烯能够改善涂层耐磨性。.

Graphene/Ni-based composite coating was prepared on 316 L stainless steel by pulsed electrodeposition process, and the coating morphology and friction properties were analyzed by experimental test. Results showed that when the amount of graphene increased, more micro-convex bodies formed on the coating surface and agglomeration phenomenon existed to a certain extent, which increased the surface roughness of the coating. As the amount of graphene in the composite plating solution increased gradually, the thickness of the composite coating increased. Each coating showed the diffraction peaks at 45°, 52°and 76° in XRD pattern, and the coating was composed of face-centered cubic Ni. The friction coefficients of the coatings obtained by adding 0.2 g/L and 0.4 g/L graphene were 3% and 12% lower than that of the substrate. The wear rate increased with the increase of load, and the composite coating added with graphene showed a decrease in wear rate. The coating made by adding 0.4 g/L graphene formed a smooth wear surface with shallow wear marks, indicating that the addition of graphene could improve the wear resistance of the coating..
