Electroplated zinc-nickel components post treated with trivalent chromate rinse were randomly selected from production lines of German automotive manufacturers. Both rack and barrel plating processes were represented among the samples. These components were then exposed to one of two accelerated corrosion environments, ASTM B 117 or GM 9540. Performance far exceeded expectations suggesting viable military use with little or no capital expenditure.
