Abstract
The invention relates to the production of protective coatings for parts of gas turbines and internal combustion engines which are to be subjected to thermal loading. A coating formed in accordance with the invention has a chemical composition and structure gradient across its thickness and an outer ceramic layer. The coating is obtained by electron beam heating of a mixture of metals (alloys) and oxides which have different vapor pressures at the evaporation temperature, the mixture and an underlying ceramic ingot being serially evaporated and subsequently condensed on the part to be coated.
