含XT铁系磷化液成膜的影响因素

The research of iron salts phosphate conversion coatings solves XT

对含XT铁系磷化液成膜的影响因素的研究结果表明，铁系磷化液使用过程中无沉渣，以XT盐为主要成分的铁系磷化液可形成优异的薄层磷化胶体膜。在50～70℃，浸泡3～5min，pH值为2～3．5时磷化成膜均匀完整，为彩虹色。总酸度在61.0～180．0点时，磷化成膜均匀完整并逐渐增厚。

The title finds XT salts come into being excerllent flexibility and good corrosion resistance folium iron phosphate conversion coatings. The salt coatings have little solubility in the process of electrophoresis. The title finds a prescription of iron salt phosphate conversion coatings solves, finds the influential facts of being conversion coatings, finds the capability of the coatings. The results indicate that the production have no precipitates and the weights of the coatings are 1.2g/m2 and the other capabilities is excellent.
