Abstract
Abstract A material and process for preparing corrosion resistant reflective material. The process in the preferred embodiment comprises abrading a metal substrate, anodizing the metal substrate, depositing a thin film of substantially pure metal on the anodized substrate, and covering the reflective metal with a protective organic coating. The material produced is a metallic substrate having an anodized layer with a relatively thin film of reflective metal covered by a protective organic coating.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
68 words
The process of preparing a corrosive resistant reflective material comprising the steps of: (a) abrading a metallic substrate to produce a slightly rough surface; (b) anodizing said metallic substrate; (c) depositing a thin film of a substantially pure metal upon the anodized substrate; (d) polishing said thin film of substantially pure metal to reflectance above about 95%; and (e) coating said reflective metal with a protective organic coating.
Claim 2
Dependent Claim
68 words
The process of preparing a corrosive resistant reflective material comprising the steps of: (a) abrading a metallic substrate to produce a slightly rough surface; (b) anodizing said metallic substrate; (c) depositing a thin film of a substantially pure metal upon the anodized substrate; (d) polishing said thin film of substantially pure metal to reflectance above about 95%; and (e) coating said reflective metal with a protective organic coating.
Claim 3
Dependent Claim
18 words
The process of claim 1 wherein said substantially pure metal is flame sprayed deposited in an inert atmosphere.
Claim 4
Dependent Claim
24 words
The process of claim 1 wherein said metallic substrate is an aluminum alloy and said substantially pure metal is aluminum above about 95% pure.
Claim 5
Dependent Claim
23 words
