Procedure

a phosphatizing solution based on: zinc phosphate diacid, nitric acid, zinc nitrate and phosphoric acid, diluted in water at 5 to 20%, at a temperature of 60 to 85° C. for a time which can vary between 5 and 15 minutes, to produce a zinc phosphate coating which is compact and uniform and has a very fine crystalline structure in order to facilitate the mechanical deformation of the material when cold;

Workup
