It can be used to reduce the size of parts when necessary. Stainless steel preferentially removes iron from the surface and enhances the chromium/nickel content for the most superior form of passivation for stainless steel. Electropolishing can be used on a wide range of metals including stainless steel, aluminum, copper, brass and titanium.
Quench polish quench (QPQ) is a specialized type of nitrocarburizing case hardening that increases corrosion resistance. It is sometimes known by the brand name of Tufftride, Tenifer or Melonite. [ 1 ]
Polishing stainless steel can also increase its sanitary benefits. The removal of oxidization (tarnish) from metal objects is accomplished using a metal polish or tarnish remover; this is also called polishing. To prevent further unwanted oxidization, polished metal surfaces may be coated with wax, oil, or lacquer.
Metal tumbling is used to burnish, deburr, clean, radius, de-flash, descale, remove rust, polish, brighten, surface harden, prepare parts for further finishing, and break off die cast runners. [citation needed] The process is fairly simple: a horizontal barrel is filled with the parts which is then rotated. Variations of this process usually ...
[5]: 393 A phosphate coating is usually obtained by applying to the steel part a dilute solution of phosphoric acid, possibly with soluble iron, zinc, and/or manganese salts. The solution may be applied by sponging, spraying, or immersion. [6] Phosphate conversion coatings can also be used on aluminium, zinc, cadmium, silver and tin. [7] [8]

There are two main process styles of aqueous parts washers, the jet spray process and the power wash process. In a cabinet parts washer, the parts are placed on a turntable and the door is closed. During the cleaning cycle heated solution is flooded or blasted on the parts as the turntable rotates. Many systems have a wash, rinse and dry cycle.
