Abstract
A composition for use in the mass finishing of metal surfaces of objects, normally in a vibratory finishing process, utilizes the combination of oxalic acid, sodium nitrate, and hydrogen peroxide. The maximum concentration of the latter is limited to a value at which excessive dissolution of metal and pitting of the surface are avoided while, at the same time, cooperating with the nitrate to effect a substantial increase in the processing rate. Highly refined surfaces are achieved with the process in relatively short periods of time.
