  • Thermal degreasing in reactive atmospheres and subsequent brazing of aluminum-based sheets or parts
    Patent number: 5016809
    Abstract: Aluminum-based sheets or parts, such as formed aluminum assemblies contaminated with forming die lubricants, are cleaned by a solventless, thermal degreasing process at controlled temperature (about 300.degree.-400.degree. F.), and in specified atmospheres (reactive gas which is at least at atmospheric pressure) prior to brazing. The organic contaminates on the aluminum-based sheet or part are reacted with the reactive gas (air or oxygen) and removed from the surface of the sheet or part without disruption of the underlying protective oxide layer. Subsequent brazing is thereby facilitated.
