ELECTRO-CHEMICAL CORROSION OF WORKING ELEMENTS

摘要

FOR THE DISCLOSURE ELECTRO-CHEMICAL CORROSION OF WORKING ELEMENTS A method of reducing the corrosion of a pair of cooperating working elements that are mounted on a frame wherein one of said elements moves relative to the other in subjecting the material being treated to a working action which comprises electrically connecting said relatively moving element to the frame of the machine thereby to maintain said relatively moving element at substantially the same potential as the frame.
