Patent number: 9186742Abstract: A brazing process and assembly utilizing microwave radiation and a plasma generator that is heated by microwave radiation and generates a localized plasma capable of selectively heating and melting a braze alloy. The plasma generator contains a microwave-susceptible material that is susceptible to heating by microwave radiation, and a plasma-generating material capable of volatilizing and generating the plasma when the plasma generator is subjected to heating and microwave radiation. The brazing process includes applying a braze material to a surface of a substrate, positioning the plasma generator in proximity to the braze material, and then subjecting the plasma generator to microwave radiation to volatilize the plasma-generating material and generate a plasma that melts the braze alloy within the braze material.Type: GrantFiled: January 30, 2009Date of Patent: November 17, 2015Assignee: General Electric CompanyInventors: Laurent Cretegny, Jeffrey Jon Schoonover
