Method for increasing the corrosion resistance of aluminum and aluminum alloys |
摘要 |
Aluminum and aluminum alloys are protected from corrosion by immersion in an alkaline lithium or alkaline magnesium salt solution. Immersion in the salt solution causes the formation of a protective film on the surface of the aluminum or aluminum alloy which includes hydrotalcite compounds. A post film formation heat treatment significantly improves the corrosion resistance of the protective film.
