Abstract

This invention concerns getters for controlled atmosphere and vacuum processes, and in particular, for processes carried out in an atmosphere having a very low oxygen content. The invention has been particularly developed for the vacuum brazing of parts, such as gas turbine components, but has a wide variety of other applications, including argon purged retort brazing and diffusion bonding.
