镀硬铬时钢铁工件的局部腐蚀与防护

Local Corrosion and Protection of Hard Cr Plated Steel Pasts

从活塞环基体的耐蚀性和微观电池腐蚀、宏观电池腐蚀、电偶腐蚀、氢去极化等方面探讨钢铁工件在镀铬过程中的腐蚀机理及腐蚀控制因素.并提出具体的防护方法.

The mechanism of local corrosion of hard chromium plated steel parts is described.The factors are discussed in detail.several practical ways of corrosion prevention are suggested in the paper.
