INTRODUCTION
In the article Chemical treatments. Introduction , we refer to the problems inherent in the highly varied surface conditions of steels as a result of their forming or finishing processes (rolled, cold or hot forged, annealed, drawn, drawn, rough cast, sintered, machined, etc.). This explains the wide variety of industrial surface preparation methods (degreasing, mechanical, chemical or mechanochemical pickling, depassivation, etc., article Degreasing in the present treatise) which are necessary to carry out a surface chemical conversion such as phosphating.
