His work primarily focuses on advancements in physical vapor deposition technologies, which are crucial for various applications, particularly in the realm of coating materials.
Latest Patents
Rigney's latest innovations include two significant patents related to electron beam physical vapor deposition (EBPVD) apparatuses. The first patent describes an EBPVD apparatus designed for producing ceramic thermal barrier coatings on articles. This apparatus operates under elevated temperatures and subatmospheric pressures, utilizing an electron beam gun to project an electron beam into the coating chamber, resulting in the melting and evaporation of the coating material. This process effectively deposits a vaporized coating onto the article within the chamber. A key feature of this design is the incorporation of a second chamber that separates the aperture from the coating region, optimizing the operational efficiency by maintaining a lower pressure in the second chamber.
The second patent outlines the method of operating this EBPVD apparatus, detailing the procedural enhancements that come into play, particularly when working at coating pressures above 0.010 mbar. This innovative approach has significant implications for the effectiveness and adaptability of coating processes in industrial applications.
