Abstract
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.
Claims8
A composite electroplated article, which comprises a metallic substrate, a first layer of nickel-iron alloy plated on said substrate and said first layer having an iron content of from about 15 to 40% by weight and a nickel content of from about 85 to 60% by weight, a second layer of nickel-iron alloy plated on said first layer and said second layer having an iron content of between about 5 and 14% by weight and a nickel content from approximately 95 to 86% by weight, a nickel layer electrodeposited on said second layer, and a layer of microdiscontinuous chromium bonded to the nickel layer.
