The copper plated aluminum shows less resistivity against corrosion due to the galvanic action caused by corrosive elements if existing. Various chemical treatments are tried in order to find the better condition for giving the anti-corrosive property to the plated aluminum.
As a result, the better anti-corrosive property is obtained by dipping it in the chromic acid bath of 30-60°C for 2-5min. The plate thus treated is 5-7 times more resistant against the salt spray than the untreated one.
