Poeton Coating Selection for medium carbon steel parts


	Coating Selection for medium carbon steel parts

Carburising (Case-Hardening) for high hardness and load-carrying capacity. Note that there may be problems of distortion.
Nitriding or Nitrocarburising if the loads are light.
Electroless Nickel and associated composites for corrosive wear situations. Hardening at 400^oC will provide additional wear resistance. Ceramic-filled electroless nickel will give further wear resistance. PTFE-filled electroless nickel will give low friction, but high wear if the load is high.
Hard Chrome Plate for excellent wear prevention. Choose the thickness on the basis of the load. E.g. Cr plate is used on car body dies. Good for corrosive wear if protected with an underlayer of electrolytic nickel.
Thermally Sprayed Metals or Alloys for wear and corrosion. E.g. tool steels.
Thermally Sprayed Ceramics or Cermets for maximum wear resistance. E.g. WC/Co, alumina, chromium oxide, etc. A corrosion barrier is required under the hard coating if corrosion is likely.
Local surface hardening (flame, induction, laser) for maximum loading, and for large rolling components (e.g. large cylindrical roller bearings and tracks).
