摘要： A PVD process and apparatus for depositing a coating from multiple sources of materials with different vapor pressures. The process entails forming molten pools of different first and second materials in a coating chamber of the apparatus, supporting an article within the chamber, and evaporating the molten pools with an energy beam to deposit a coating on the article with a controlled composition that contains at least a first metal and a relatively lesser amount of at least one reactive metal having a lower vapor pressure than the first metal. The first material contains at least the first metal, and the second material contains the reactive metal and at least a second metal. The second and reactive metals are combined to cause the second material to have a lower melting temperature and wider melting range than the reactive metal.

摘要： A coating and process for depositing the coating on a substrate. The coating is a nickel aluminide overlay coating of predominantly the beta (NiAl) and gamma-prime (Ni3Al) intermetallic phases, and is suitable for use as an environmental coating and as a bond coat for a thermal barrier coating (TBC). The coating can be formed by depositing nickel and aluminum in appropriate amounts to yield the desired beta+gamma prime phase content. Alternatively, nickel and aluminum can be deposited so that the aluminum content of the coating exceeds the appropriate amount to yield the desired beta+gamma prime phase content, after which the coating is heat treated to diffuse the excess aluminum from the coating into the substrate to yield the desired beta+gamma prime phase content.
