Nickel phosphatation of HSLA steels

Posted by Massimo Bocca on July 12, 1996 at 16:43:39:

I'm interested in the evaluation in the performances of
different formulations of phosphate metallic salts in
preventing corrosion in automotive steel parts. My
problem is in finding some hints regarding the
relationship between material properties (i.e. surface
percentage of carbon) and different compositions of the
phosphatation bath (i.e, bi/tricationic phosphatation).

Have you any experience in such a field? I would be
most grateful if you could possibly give me some help.

Thanx in advance,
