Brazing of Materials for Aerospace Applications

Developing joining technologies to produce advanced components with unique properties is attracting attention for aerospace applications. Brazing is one of the most reliable processes for the aerospace industry to obtain sound joints between dissimilar materials. This process takes place within a vacuum furnace or under controlled atmospheric conditions to produce strong bonds with notable resistance against corrosion and oxidation. This chapter presents the latest approaches to brazing similar and dissimilar materials for aerospace applications. The selection of brazing alloys is an essential step in this process. As such, the commonly used brazing alloys, such as those based on titanium or silver, and the new alloys being developed in this field will also be presented. Emphasis is placed on self-propagating high-temperature systems, nanomaterials, composite fillers, and amorphous filler metals.
