Abstract
A sputtering method and target for depositing a crack-resistant metal coating on plastic is described. The target consists essentially of Cr, 5 to 30% Fe and 0 to 5% scavenger elements. Al, Ce, La, Ti and Zr, among others, are preferred scavengers. ABS plastic is a preferred substrate. The coated articles have the appearance of bright chromium metal, and are useful as automotive trim.
