渗氮技术在离心泵叶轮上的应用

Application of Liquid Nitride Technology in Pump Impeller

真空制盐工况中腐蚀严重,很多设备因腐蚀严重而降低使用寿命,文章所述渗氮防腐技术,为该工况材料选择开辟了一个新的方向。成功应用氮化处理叶轮的离心泵,证明了该方式可行,同时这种处理方式可以大幅降低生产成本。

There was severe corrosion in vacuum salt condition,which a lot of equipment reduced service life because of the severe corrosion. The nitride anticorrosion technology has opened up a new direction for the condition of material selection. It is proved that this method is feasible and the treatment method can reduce the production cost.
