Abstract

Process for the surface treatment of metals, in particular iron, by using an aqueous acid solution based on alkali metal and/or ammonium orthophosphate at a ph between 3.0 and 5.5 per spray under pressure, characterized in that the solution is sprayed onto the surfaces to be treated under a pump pressure of approximately 10 to 75 atmospheres.
