nitridingn.

Brit.

/ˈnʌɪtrʌɪdɪŋ/,

/nʌɪˈtrʌɪdɪŋ/, U.S.

/ˈnaɪˌtraɪdɪŋ/

Origin: Formed within English, by derivation. Etymons: nitride v., -ing suffix¹.

Etymology: < nitride v. + -ing suffix¹.

The process of converting a substance into a nitride or nitrides; (Metallurgy) the process of heating a ferrous alloy in the presence of ammonia or another nitrogenous substance so as to form nitrides near the surface, thus improving hardness and corrosion resistance. Usually attributive. nitriding steel n. steel that is suitable for nitriding.
