Ce(SO 4 ) 2 濃度對(duì)電噴鍍Ni-W-Ce合金鍍層性能影響(英文)
發(fā)布時(shí)間:2021-06-05 05:00
為了研究Ce(SO4)2濃度與合金鍍層表面性能的關(guān)系,采用電噴鍍制備了一系列Ni-W-Ce合金鍍層工件。用掃描電鏡(SEM)觀察了鍍層的表面結(jié)構(gòu),并用能譜儀(EDS)檢測(cè)鍍層中的元素組成。用XRD分析鍍層的物相組織,表明Ce(SO4)2加入后鍍層發(fā)生晶格畸變。使用CFT-Ⅰ型材料表面綜合性能測(cè)試儀在鍍層表面進(jìn)行磨痕制備,并通過(guò)LEXT4100激光共焦顯微鏡和SEM觀察磨痕形貌,表征鍍層耐磨性和磨損機(jī)理。結(jié)果表明,添加Ce(SO4)2改善了涂層的表面微觀形貌,當(dāng)其濃度為0.5 g/L時(shí),涂層的表面質(zhì)量最佳。同時(shí),顯微硬度、耐磨性和耐腐蝕性隨濃度的增加呈現(xiàn)先好后壞的規(guī)律。當(dāng)Ce(SO4)2濃度為0.5 g/L時(shí),鍍層顯微硬度、耐磨性和耐腐蝕性均取得最佳,此時(shí)的顯微硬度數(shù)值達(dá)到峰值5196.9 MPa,其耐磨性表征參數(shù)均取得最小值,且腐蝕電位為-0.5537V,電弧電抗半徑最小。
