A process is disclosed comprising a method for treating and conveying gas mixtures in a coating process employing a chemical, heterogeneous vapor-phase reaction in a reaction chamber in which the reaction product obtained in the reaction chamber is withdrawn from the reaction chamber, separated into at least one component, the withdrawn component is dosed and reintroduced into the reaction chamber.

Method for conveying and treating a gas employed for the coating of

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.

Method of producing protective oxide layers

Method for the manufacturing of deformation-resistant oxide coatings on metallic workpieces, in which fissures are induced in the oxide layer formed on the surface of the workpiece as a result of severe deformations in the base material. The fissures are subsequently healed by filling the interstices with subsequently produced oxide resulting from a post-oxidation process. Repeating the process several times controls the natural stress condition of the surface layer such that the effective elastic deformation range is extended.
