Zinc-phosphate coating and 1x cataphoretic soaking.

September 30, 2012

Q. DEAR SIR,

I am a development Engineer, working with an Automobile company at India.
I have to develop a break pedal lever. For which, on steel lever the zinc phosphating coating and 1x cataphoretic soaking is required. So I want to know the entire process for this required surface treatment.
colour-black: half matte
thickness: 15-25 µm

A. Hi, Vishnu.

I am having some trouble with your terminology, and am not quite sure whether you are asking about a topic I am unfamiliar with, or whether there has just been some language/translation difficulties. I haven't heard of "1X Cataphoretic Soaking", but maybe you are speaking of what I would call CED (cathodic electrodeposition) coating.

The overall sequence would probably be something like: Soak clean, rinse, acid dip, rinse, zinc phosphate, rinse, DI rinse, CED tank, recovery rinse, rinse. -- although other readers will hopefully refine or further elaborate their preferences for the processing sequence.

Regards,

Ted Mooney, P.E.
