Abstract : Electroplated zinc/nickel components posttreated with trivalent chromate rinse were randomly selected from production lines of a German automotive manufacturer. 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 (Standard Method of Salt Spray [Fog] Testing, Annu. Book ASTM Stand., 1997) or GM 9540 (Accelerated Corrosion Test; General Motors Engineering Standards, 1997). Performance under accelerated corrosion conditions far exceeded expectations suggesting viable military use with little or no additional capital expenditure.
