DEFINITION

Classification: 505/470

Coating:

(under subclass 300) Process that includes a step of (a) applying or obtaining on a surface of a substrate a layer of differing composition, or (b) permeating a porous substrate with a material of composition differing from the original substrate.

(1) Note. Complete oxidation of a material forming a new composition is not considered a coating process, even though it may be a coating that is completely oxidized. However, if oxidation occurs simultaneously with deposition of a material upon a substrate, this is viewed as a coating operation.
