Abstract
A method for superfinishing a high density carbide steel component using chemically accelerated finishing is provided. The high density carbide steel component is vibrated in a vessel containing a plurality of media, with active chemistry being added to the vessel at a low flow rate. An active chemistry composition is also provided, consisting of one or more conversion coating agents having preferably a phosphate radical, and one or more chelating agents preferably including citric acid.
