DEFINITION

Classification: 148/518

With electrocoating (e.g., electroplating, anodizing, sputtering, etc.):

(under subclass 516) Process which includes a step of electrocoating (e.g., electroplating, anodizing, etc.) by application of an externally supplied electrical current or by sputtering.

(1) Note. If during a post-treatment operation the substrate becomes subjected to a Class 148 treatment that goes beyond the mere interdiffusion at the interface to perfect the coating, placement goes in this subclass whether or not the coating layer is involved. However, an electrocoating step must be present for this subclass.

205, Electrolysis: Processes, Compositions Used Therein, and Methods of Preparing the Compositions, appropriate subclasses for processes involving electrocoating of metal substrates and which include Class 148 operations as herein defined which are preparatory to the electrocoating or are posttreatment operations limited to the coating layer or involving diffusion affecting only the interface. Electrorefining is not considered to be electrocoating in Class 205 or for this subclass in Class 148.
