| titleOfInvention | Non-chromated surface preparation materials and methods for corrosion protection of aluminum and its alloys |
| abstract | Surface preparation methods (10) and materials that provide corrosion protection for aluminum and its alloys without the use of chromate and that protects aluminum against corrosion nearly as well as a chromate conversion coating. In accordance with the present methods (10), aluminium parts are degreased (11) in a general purpose cleaner and rinsed (12) in hot tap water. The parts are then cleaned (13) using alkaline cleaner and then rinsed (14) in cold tap water. The parts are then deoxidized (15) using one of two alternative steps. The parts may be deoxidized (15a) using a 20-25 volume percent Smut-Go NC solution at room temperature for 15-25 minutes. The parts may alternatively be deoxidized (15b) using a solution of 10%HNO3 and 3% NaBrO4 dissolved in water at room temperature for 15-25 minutes. Thedeoxidized aluminum parts are then rinsed (16) in cold tap water. The parts are then immersed (17) in boiling deionized water and then sealed (18) using a 1% LiNO3, 10% Al(NO3)3 and 10% aluminum silicate solution. The sealed parts are sealed (20) a second time using a solution of 13-15% Kasil #1 with a dissolved corrosion inhibitor. The sealed parts are finally dried (21) in air for about 24 hours or in an oven for 3-4 hours at 150 degrees Fahrenheit. Aluminum parts treated by the present methods (10) meet the requirements of MIL-C-5541 without using hazardous chemicals. |
