Abstract
A method for producing oxide surface layers on titanium-based objects. The object is pretreated mechanically and, following pretreatment, an oxidation process takes place using a low oxidation potential and a temperature between 480.degree. C. and 800.degree. C. As an oxidizing agent, use is preferably made of water vapor at a partial pressure of about 20 mbar. The water vapor may be mixed with an inert carrier gas, such as argon or helium.
