Noun
(metallurgy) An industrial process for case hardening (imparting greater surface hardness to) metal objects, involving nitrocarburizing (the diffusion of carbon and nitrogen into the metal) followed by oxidation.
(underwater diving) A mixture of nitrogen and oxygen, the nitrogen content being lower than that of normal air, which is used in place of air as a breathing gas.

All of these steps minimize danger but increase complexity of operations (for example, personalized cylinders for each diver must generally be kept track of on dive boats with nitrox, which is not the case with generic compressed air cylinders). Source: Internet
Breathing gases for scuba main seeAlso Until nitrox was widely accepted in the late 1990s, almost all recreational scuba used simple compressed and filtered air. Source: Internet
Dangers Oxygen toxicity main Diving with and handling nitrox raise a number of potentially fatal dangers due to the high partial pressure of oxygen (ppO 2 ). Source: Internet
A position which it would formally maintain until in 1995 magazine editor Bill Gleason was reported to say that nitrox was "all right". Source: Internet
In 1993 Skin Diver magazine, the leading recreational diving publication at the time, published a three-part series arguing that nitrox was unsafe for sport divers. Source: Internet
