a type of case-hardening in which steel is heated for long periods in ammonia vapour so that nitrogen produced by dissociation on the surface enters the steel
nitriding in American English
(ˈnaitraidɪŋ)
noun
Metallurgy
a process of casehardening in which nitrogen is introduced into the metal by keeping it at a suitable temperature in the presence of a nitrogen source
Word origin
[nitride + -ing1]-ing is a suffix of nouns formed from verbs, expressing the action of the verb or itsresult, product, material, etc. (the art of building; a new building; cotton wadding). It is also used to form nouns from words other than verbs (offing; shirting). Verbal nouns ending in -ing are often used attributively (the printing trade) and in forming compounds (drinking song). In some compounds (sewing machine), the first element might reasonably be regarded as the participial adjective, -ing, the compound thus meaning “a machine that sews,” but it is commonly taken as a verbalnoun, the compound being explained as “a machine for sewing”
