Abstract
Reflective coating systems, methods for depositing such coating systems, and lamps equipped with such coating systems. The reflective coating systems include an intermediate metallic layer overlying a substrate and consisting of nickel, chromium or a Ni—Cr alloy, a reflective metallic layer containing silver and overlying the intermediate metallic layer, and a protective layer overlying the reflective metallic layer.
Claims20
A reflective coating system on a surface of a substrate, the reflective coating system comprising an intermediate metallic layer overlying the substrate and consisting of nickel, chromium, or a Ni—Cr alloy, a reflective metallic layer containing silver and overlying the intermediate metallic layer, and a protective layer overlying the reflective metallic layer.
A lamp comprising a substrate and a reflective coating system on a surface of the substrate, the reflective coating system comprising an intermediate metallic layer overlying the substrate and consisting of nickel, chromium, or a Ni—Cr alloy, a reflective metallic layer containing silver and overlying the intermediate metallic layer, and a protective layer overlying the reflective metallic layer.
A method of producing a lamp having a reflective interior surface, the method comprising:
- depositing an intermediate metallic layer consisting of nickel, chromium, or a Ni—Cr alloy to overlie a substrate of the lamp;
- depositing a reflective metallic layer containing silver to overlie the intermediate metallic layer;
- and
- depositing a protective layer to overlie the reflective metallic layer.
