A system for the passivation of metal surfaces, and more especially those of stainless steel, titanium, etc., in equipment used for chemical processes, where elements and compounds are formed which have a corrosive action, in particular where temperature and pressure are higher than ambient conditions. In the system the main passivating agent is oxygen (air) combined with at least a second auxiliary agent, characterized by the fact that the latter is ozone (03).
