Phosphating on Decarburised Layer


Dear readers,

This is a query regarding phosphating. Does the 'adherence value' of phosphating get affected by the presence of decarburised layer present on surface of carbon steel components? If yes, then how? Please give me the response as early as possible. Thanks.

I am sure that many carbon steel parts have been unwittingly decarburized and then unwittingly phosphated. A controlled finishing process of the parts and processing will keep adhesion at an acceptable level. An abused surface will always cause finishing problems. Regards, Tom

Dear tom,
As decarburised layer consists predominantly of FeO, isn't it possible that Fe in free condition is not available for the reaction to get completed. just a query
