锌钙系防锈磷化工艺

The Zinc Calcium Guards Against Rust the Phosphorization Craft

研究了锌钙系磷化工艺.以磷化膜质量和防锈性为定量指标,讨论了操作参数(总酸度、游离酸度、温度、时间和酸比)对磷化膜的影响,确定了最佳磷化工艺.结果表明:该磷化工艺稳定,维护简单,所得磷化膜防锈性优良.由磷化机理分析表明,磷化膜的组成为Zn3(PO4)2和Ca3(PO4)2.

This paper studies the zinc calcium phosphorated craft. Take phosphorated quality and rust prevention as the quota target, it interprets the operation parameter, （ total acidity, free acid acidity, temperature, time and acid lompares） to phosphorize the effect, and determines the best phosphorated craft. The result indicates that： this phosphorated craft is stable, with simple maintenance. The obtained phosphorizated membrane rust prevention is fine. The phosphorization mechanism analysis indicates that the phosphorization membrane composition is Zn3 （ PO4 ） 2 and Ca3 （ PO4 ） 2.
