| titleOfInvention | The method for cleaning surface of aluminum alloy forge piece |
| abstract | The present invention proposes a kind of method for cleaning surface of aluminum alloy forge piece, including：The cleaning that the aluminum alloy forge piece that carbon particle is contained on surface is followed the steps below；First pickling；First alkali cleaning；Light；Soaked in cutting fluid；Second alkali cleaning；Second pickling；Soaked in water；And dry.Need to soak in cutting fluid in the technique of the present invention, can so accelerate the sinking speed of carbon particle, improve operating efficiency, while the lubricating film of densification can also be formed on the surface of aluminum alloy forge piece prevents surface oxidation.The mixed acid of nitric acid and phosphoric acid is selected in first pickling so that the finish on the aluminum alloy forge piece surface after washing is preferable, and the ability of degreasing is also stronger.This process increases production efficiency, production cost, and maturation simple to operate are reduced, is suitable for large-scale promotion application. |
