Abstract
An article is coated with a multi-layer coating having the appearance of nickel. The coating comprises one or more electroplated layers on the surface of said article, and vapor deposited on the electroplated layers a stack layer comprised of alternating layers of refractory metal compound or refractory metal alloy compound alternating with refractory metal or refractory metal alloy, and on said stack layer a refractory metal nitride or metal alloy nitride color layer where the nitrogen content of said nitride is from about 6 to about 45 atomic percent, and which is vapor deposited under relatively low pressure.
Claims24
An article having on at least a portion of its surface a multi-layer coating having a nickel color comprising:
- at least one layer comprised of nickel;
- a stack layer comprised of plurality of alternating layers comprised of refractory metal compound or refractory metal alloy compound alternating with layers comprised of refractory metal or refractory metal alloy;
- vapor deposited color layer comprised of refractory metal nitride or refractory metal alloy nitride wherein said nitrogen content of said refractory metal nitride or refractory metal alloy nitride is from about 6 to about 45 atomic percent and wherein said color layer is deposited at a pressure of below about 8 millitorr.
