Abstract
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.
Claims38
A method for depositing a deposition material on a part comprising:
- placing the part in a deposition chamber;
- vaporizing one or more first components for forming the deposition material by electron beam heating;
- and
- vaporizing one or more organometallic compounds for providing one or more second components of the deposition material being codeposited on the part with the first components, wherein:
- the part has lost first material from a site;
- and
- the deposition material is deposited to the site so as to replace the lost first material.
