METHOD OF PRODUCING PROTECTIVE DECORATIVE MULTILAYER COATINGS

摘要

Substantially improved results by way of durability and appearance are accomplished by electrodepositing upon a metallic substrate a plurality of layers of a nickel-iron alloy, the lowermost of which has a relatively high iron content and the uppermost a relatively lower iron content, upon which is electrochemically bonded a nickel layer and an upper layer of microdiscontinuous chromium or equivalent decorative finishing material.
