Mr.P.Senthamaraikannan, M.E., (Ph.D). Plasma nitriding/nitrocarburising is a modern thermochemical treatment which is carried out in a mixture of nitrogen, hydrogen and an optional carbon spending gas. In plasma nitriding, the reactivity of the nitriding media is not due to the temperature but to the gas ionized state.
