Method of adherency of electrodeposits on light weight metals |
摘要 |
A plated aluminum product, and the method of making such product is disclosed for use in automotive bumpers. A plated outer decorative coating is used and is preferably constituted of chromium (0.000005-0.00005'' thick) on nickel (0.0003-0.003'' thick.) An electroplated pretreatment system is employed between the outer decorative coating and aluminum alloy and consists essentially of at least a brass strike containing, for purposes of increased lateral corrosion resistance, an as-deposited copper content in the range of 60-75% by weight, and the aluminum substrate should preferably be restricted to a zinc content of 4.5-5.5%.
