Ce(SO 4 ) 2 浓度对电喷镀Ni-W-Ce合金镀层性能影响(英文)
发布时间:2021-06-05 05:00
为了研究Ce(SO4)2浓度与合金镀层表面性能的关系,采用电喷镀制备了一系列Ni-W-Ce合金镀层工件。用扫描电镜(SEM)观察了镀层的表面结构,并用能谱仪(EDS)检测镀层中的元素组成。用XRD分析镀层的物相组织,表明Ce(SO4)2加入后镀层发生晶格畸变。使用CFT-Ⅰ型材料表面综合性能测试仪在镀层表面进行磨痕制备,并通过LEXT4100激光共焦显微镜和SEM观察磨痕形貌,表征镀层耐磨性和磨损机理。结果表明,添加Ce(SO4)2改善了涂层的表面微观形貌,当其浓度为0.5 g/L时,涂层的表面质量最佳。同时,显微硬度、耐磨性和耐腐蚀性随浓度的增加呈现先好后坏的规律。当Ce(SO4)2浓度为0.5 g/L时,镀层显微硬度、耐磨性和耐腐蚀性均取得最佳,此时的显微硬度数值达到峰值5196.9 MPa,其耐磨性表征参数均取得最小值,且腐蚀电位为-0.5537V,电弧电抗半径最小。
