| titleOfInvention | A method of improving aluminum alloy surface corrosion resistance |
| abstract | The invention discloses a kind of methods for improving aluminum alloy surface corrosion resistance, are related to technical field of aluminum alloy technology, comprising the following steps: and aluminium alloy test specimen is cleaned using acetone soak (1), is then cleaned again using deionized water, drying；(2) surface uniform grinding is carried out using to above-mentioned aluminium alloy test specimen；(3) aluminium alloy test specimen is impregnated using potassium hydroxide solution, then takes out, is cleaned using clear water, dried；(4) aluminium alloy test specimen is put into and is crossed in coating solution, after impregnating 12-15s, amino silicone is added into coated solution, 30-32s is stirred, then adds triethanolamine into coated solution again, stirs 35-40s, then polynary amine aqueous solution is added again, 30-32s is stirred, aluminium alloy test specimen is taken out in heat preservation, drying, then cooled to room temperature again, cleans aluminium alloy test specimen using ethanol solution, dry；By the method for the present invention, treated that aluminium alloy surface of test piece is capable of forming one layer of fine and close plated film, the protection effect played to aluminium alloy that can be effective. |
