  • Electrolytically treating a selected cylindrical surface of an article
    Patent number: 4042467
    Abstract: A cylindrical surface of an article is electrolytically treated with a controlled, cross-sectional distribution of the electrolytic action. The distribution is achieved by placing the surface at a predetermined distance from a formed electrode to control the influence of the electrode on each portion of the surface along a cross section thereof. The influence on each such portion with respect to other portions of the surface is determined by the magnitude of an influence number associated with such portion in relation to the magnitude of similar influence numbers associated with the other surface portions along the cross section.
