Process for producing part made of magnesium and/or magnesium alloy

(after amendment) A process for preparing a treated magnesium and/or magnesium alloy component comprising (A) treating the magnesium and/or magnesium alloy component with a surface treating agent containing at least one compound selected among ammonium salts or alkanolamine salts of phosphoric acids as a phosphate,

• (B) treating the component with a pre-treating agent used before a corrosion inhibition treatment, and thereafter
• (D) treating-the component with a corrosion inhibitor for magnesium.

(after amendment) A process for preparing a treated magnesium and/or magnesium alloy component comprising (A) treating the magnesium and/or magnesium alloy component with a surface treating agent containing at least one compound selected among ammonium salts or alkanolamine salts of phosphoric acids as a phosphate,

• (B) treating the component with a pre-treating agent used before a corrosion inhibition treatment,
• (C) treating the component with a cleaning agent containing surfactant and at least one compound selected from among aromatic carboxylic acids and salts thereof, and thereafter
• (D) treating the component with a corrosion inhibitor for magnesium.
