  • Composition for plasma electrolytic oxidation (PEO) treatment of magnesium alloy products
    Patent number: 8337689
    Abstract: Disclosed herein is a composition for plasma electrolytic oxidation (PEO) treatment of magnesium alloy products, which contains a sodium hydroxide (NaOH) solution as a main component, the composition comprising, based on the weight of sodium hydroxide contained in the sodium hydroxide solution: 1-20 wt % of sodium fluoride (NaF); 1-15 wt % of trisodium phosphate (Na3PO4); 1-10 wt % of sodium pyrophosphate (Na4P2O7); 1-20 wt % of aluminum hydroxide (Al(OH)3); 1-20 wt % of sodium fluorosilicate (Na2SiF6); 1-10 wt % of potassium hydroxide (KOH); 1-15 wt % of potassium acetate (C2H3O2K); and 1-10 wt % of rare earth metal powder. The disclosed composition can form a firm, dense and uniform oxide film on the surface of a magnesium alloy product.
