Using the electrolytic-abrasive mirror finishing method, a large area of stainless and ordinary steel metal works can be easily mirror-finished in a short time and with high efficiency up to a surface roughness of 0.01-0.02μm Rmax. This method is based on the fact that the electrolytic action is assisted by the removing action of abrasive grains within an appropriate current density range by using of passivation type electrolytes.
This paper, first of all, describes the basic characteristics of surface finishing on planes, cylindrical works and curved surfaces when this method is used. Furthermore, it introduces the results of using the electrolytic-abrasive mirror finishing method in a few typical applications: a chemical reactor, stainless steel substrate for amorphous sillicon solar cells, a large-size cylindrical work in a diesel engine, etc.
