DEFINITION

Classification: 205/170

Forming multiple superposed electrolytic coatings:

(under subclass 80) Subject matter wherein a plurality of distinct superposed electrolytic coatings are formed on a substrate.

(1) Note. A single coat, layer, or film built up of a series of substantially identical coatings, one superimposed or added to the other or others, is not placed here but may be found in the appropriate subclass dependent upon the composition of the layer or coat formed. For example, a process of coating copper on a rotating surface that is repeatedly immersed in the electrolyte and withdrawn will be found in subclass 143 even though a great number of thin films join together to form one distinct coat.
