  • Patent number: 6589608
    Abstract: A process for producing a homogeneous oxide layer on metal components includes uniformly heating the components, in all their regions, in a vacuum chamber and, after a predetermined temperature has been reached, exposing the components to an oxygen-containing gas for a predetermined period and at a predetermined pressure. The metal components are coated with MCrAlY or PtAl. The preheating temperature is between 750 and 850° C., preferably, approximately 800° C. Preferably, the thickness of the homogeneous oxide layer is between 0.01 and 5 &mgr;m. The heating is preferably by electron radiation. The predetermined period is approximately 10 minutes, and the predetermined pressure is between 1×10−3 and 8×10−2 mbar.
