METHOD AND COMPOSITION FOR REFINEMENT OF METAL SURFACES

摘要

A composition for use in the vibratory mass finishing of magnetic stainless steel objects contains oxalic acid, sodium m-nitrobenzene sulfonate, and sodium thiocyanate, the latter two compounds being present in specified ratios to one another. The preferred compositions include a hydroxyalkyl amine; for certain applications, they most desirably also include a poly(oxyethylene)-alkyl alcohol surfactant.
