| description | A composition for use in the process of mass finishing of metal surfaces of objects, normally in a vibratory finishing process, utilizes a combination of oxalic acid, sodium nitrate, and hydrogen peroxide. The maximum concentration of the latter in an aqueous solution used in the process is limited to a value (0.05 gram mole/l) 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 using the process in relatively short p eriods of time. |
