Controllable oxidation of certain titanium zirconium alloys is achieved by utilizing minor proportions of niobium, tantalum or vanadium or mixtures thereof, and articles formed therefrom can be partially oxidized to form a deep, hard monolithic oxide containing surface layer and further or completely oxidized to form a cermet or ceramic body, respectively. On maîtrise l'oxydation de certains alliage de titane-zirconium en utilisant des proportions mineures de niobium, de tantale ou de vanadium ou de mélanges de ces derniers. Les articles produits à partir de ces derniers peuvent être partiellement oxydés pour former une couche superficielle contenant, en profondeur, un oxyde monolithique dur, et encore plus ou complètement oxydés pour former un cermet ou un corps en céramique.
