WebDec 18, 2024 · The plasma nitriding process involves the diffusion of nitrogen to the surface of the electroplated coating, which results in the formation of a hard chromium nitride layer. The chromium nitride layer, which can be in the form of CrN or Cr2N, improves the corrosion resistance of the electroplated coating by occluding the surface microcracks. WebThe oxidised samples and ground reference samples were plasma nitrided together in an active screen plasma nitriding (ASPN) furnace. It was found that the ground samples were nitrided as normal - as indicated by the formation of an iron nitride compound layer and considerably improved hardness of the nitrided surface.
WebThe active screen plasma nitriding (ASPN) is a novel plasma assisted nitriding technique with a high application potential [3]. The main advantages of the ASPN over a conventional plasma process are caused by the replacement of the glow discharge from the ...
