Abstract

PURPOSE: To form an oxide coat with superior corrosion and wear resistances on the surface of Al by plasma-oxidizing the Al surface after applying an aqueous Al salt soln.
CONSTITUTION: An aqueous Al salt soln. is applied to the surface of Al to form an Al salt film. The soln. is preferably used at 5W30wt% concn. and applied by 1W 50mg/cm2, and the treating temp. is generally about 10W60°C. As the Al salt, an acidic Al salt such as aluminum sulfate or a basic Al salt such as sodium aluminate is used. The Al surface with the formed Al salt film is then plasma-oxidized with a plasma incinerator. When org. matter remains on the Al surface, by the plasma oxidation it is forced to be burned, so no org. matter hinders the formation of an oxide coat. By regulating the kind, amount and concn. of the Al salt soln., the thickness of the resulting oxide coat can be regulated simply.
