Document Type and Number:
Japanese Patent JP4348464
Kind Code:
B2
Abstract:
Method of electrolytically continuously treating a material of stainless steel at a current density of 0.1-3 A/cm2, wherein the material is passed through one or more electrolytic cells arranged in series. The cells contain an electrolyte selected from sulphuric acid, a salt thereof, phosphoric acid and nitric acid, and the material is passed through the electrolyte between electrodes arranged in series under the influence of a direct current with alternating polarity. The electrodes are arranged alternately anodic and cathodic and every electrode on one side of said material is matched by an electrode of the same polarity on an opposite side of the material, whereby an oxide surface layer with a thickness of at least 1 micrometer is removed from the material to produce a surface conditioning effect.
