Coated Article With Dark Color

摘要

An article is coated with a coating having a dark color. In a preferred embodiment, the coating comprises a nickel or polymer basecoat layer, and a first color layer comprised of oxygen-rich refractory metal oxycarbides, a second color layer comprising oxygen-rich refractory metal oxycarbides and a top layer of refractory metal oxides.

主权项

1. A coated article having a black color comprising a substrate having a surface and having on at least a portion of the surface a multi-layer coating comprising in order:
a first layer of a refractory metal oxycarbide having an oxygen content and a carbon content wherein the oxygen content is greater than the carbon content wherein the refractory metal oxycarbide of the first color layer is 20 to 35 atomic percent oxygen, 10 to 20 atomic percent carbon and 50 to 70 atomic percent refractory metal, a second color layer on top of the first color layer, wherein the second color layer comprises a layer of refractory metal oxycarbide having an oxygen content and a carbon content wherein the oxygen content is greater than the carbon content; and wherein the oxygen content of the second color is greater than the oxygen content of the first color layer wherein the refractory metal oxycarbide of the second color layer is 40 to 65 atomic percent oxygen, 5 to 20 atomic percent carbon and 25 to 50 atomic percent refractory metal; and a refractory metal oxide layer on top of the second color layer;wherein the first layer has a dark gray color, the second layer has a dark pray color, the top layer has a yellow color and the article has a black color.
