Abstract
A coated article includes a substrate, a first ceramic layer deposited on the substrate, a color layer deposited on the first ceramic layer, and a second ceramic layer deposited on the color layer. The first ceramic layer substantially includes substance M, elemental O and elemental N, wherein M is Al or Si. The color layer substantially includes metal M′, O and elemental N, wherein M′ is elemental Al or Zn. The second ceramic layer substantially includes substance M, elemental O and elemental N, wherein M is Al or Si.
Claims20
A coated article, comprising:
- a substrate;
- a first ceramic layer deposited on the substrate, the first ceramic layer consisting essentially of substance M, elemental O and elemental N, wherein M is Al or Si;
- a color layer deposited on the first ceramic layer, the color layer consisting essentially of metal M′, elemental O and elemental N, wherein M′ is Al or Zn;
- and
- a second ceramic layer deposited on the color layer, the second ceramic layer consisting essentially of the same substance M as in the first ceramic layer, elemental O and elemental N.
A method for manufacturing an article comprising:
- providing a substrate;
- depositing a first ceramic layer, the first ceramic layer having a first outer surface away from the substrate, the first ceramic layer substantially including substance M, elemental O and elemental N, wherein the M is Al or Si, during deposition of the first ceramic layer, N2 and O2 used as reaction gases, the first targets are made of Al, Al alloy, Si or Si alloy;
- polishing the first outer surface;
- depositing a color layer on the first ceramic layer, the color layer consisting essentially of substance M′, elemental O and elemental N, wherein the M′ is elemental Al or Zn, during deposition of the first ceramic layer, N2 and O2 used as reaction gases, the second targets are made of Al, Al alloy, Zn or Zn alloy;
- depositing a second ceramic layer on the color layer, the second ceramic layer having a first outer surface away from the color layer, the second ceramic layer consisting essentially of substance M, elemental O and elemental N, wherein the M is Al or Si, during deposition of the second ceramic layer, N2 and O2 used as reaction gases, the first targets are made of Al, Al alloy, Si or Si alloy;
- polishing the second outer surface.
