A method for depositing a first material on a substrate includes providing the substrate in a deposition chamber. A molten body is formed between the substrate and a source of the first material by melting one or more second materials. A flow of the first material is passed through the molten body and from the molten body to the substrate as a vapor flow. An essentially non-expending portion of the molten body comprises an alloy having a melting temperature below a melting temperature of the first material.

Vapor deposition of dissimilar materials

Physical vapor deposition is augmented by chemical vapor deposition from one or more organometallic compounds to deposit multi-component materials. The organometallic compounds may be carbonyls. The process may be used to deposit coatings and repair material on superalloy turbine engine parts.

Multi-component deposition

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.
