水冷管泄漏机理的电子探针分析

Identification of Corrosion Products on the Walls of Water-cooling Pipes by EPMA and EDX

利用电子探针和X -射线能谱仪对发电机水冷管的金属腐蚀物进行分析 ,发现金属腐蚀是由磷酸盐及设备中各部位材料不同引起的 ,而除垢剂的使用是金属腐蚀产生的主要原因。

EPMA and EDX methods have been employed to identify the corrosion products on the walls of water _ cooling pipes of power generators. The presence of phosphates and the contact of dissimilar metals cause metal corrosion. The major cause is the presence of residual chemical reagents for the removal of scales.
