DEFINITION

Classification: 205/669

Using surface tension or capillary action to hold electrolyte in contact with workpiece:

(under subclass 668) Process in which the electrolyte is held into contact with a portion of the workpiece surface by surface tension or capillary action.

(1) Note. The surface tension forces may be due to an adjacent gas or an immiscible liquid.
