Tribological performance of coumarin in copper rolling oil was studied by four-ball tests and cold rolling tests. Then a systemic investigation on surface topography and surface chemistry of rolled strips was performed by field emission scanning electron microscope (FE-SEM), laser scanning confocal microscopy (LSCM), x-ray diffraction (XRD), x-ray photoelectron spectroscopy (XPS) and Raman spectroscopy (Raman). Results showed that coumarin was a kind of potential lubrication additive. The average friction coefficient (AFC) and wear scar diameter (WSD) were reduced by 30.2% and 30.1%, respectively, when the optimum concentration of coumarin (2.0 wt%) was added in copper rolling oil. Meanwhile, as the formation of tribofilm during rolling process, the nonuniform deformation and adhesive wear were effectively inhibited. Thinner copper strips with fine surface quality were obtained. The surface average roughness (Sa) of rolled copper strips was reduced by up to 68.8%. Surface charac...

通过表面表征研究香豆素作为轧制铜油添加剂的摩擦学行为

通过四球试验和冷轧试验研究了香豆素在铜轧制油中的摩擦学性能。然后通过场发射扫描电子显微镜(FE-SEM),激光扫描共聚焦显微镜(LSCM),X射线衍射(XRD),X射线光电子能谱(XPS)对轧制带材的表面形貌和表面化学进行了系统研究)和拉曼光谱(Raman)。结果表明,香豆素是一种潜在的润滑添加剂。当在铜轧制油中添加香豆素的最佳浓度(2.0 wt%)时,平均摩擦系数(AFC)和磨痕直径(WSD)分别降低了30.2%和30.1%。同时,由于在轧制过程中形成了摩擦膜,有效地抑制了不均匀变形和胶粘剂磨损。获得了具有良好表面质量的较薄铜带。轧制铜带的表面平均粗糙度(Sa)降低了68.8%。表面特性
