    摘要: A process for forming a protective coating for protecting a substrate metal from corrosion and improving the adhesion of subsequently applied coatings, comprising treating the metal with an aqueous acidic solution containing molybdate in an amount of from 0.01 to 10.0 g/l, chromium in an amount of from 0.01 to 10.0 g/l, fluoride in an amount of from 0.01 to 10.0 g/l, phosphate in an amount of from 0.01 to 10.0 g/l, zinc in an amount of from 0.005 to 1.0 g/l, and acetate in an amount of from 0.01 to 10.0 g/l. The process successfully treats a variety of metals, and provides high-quality coated composites.
