Abstract : Test results show that the Na2Cr207-H2SO4 (Convair FPS-0003) cleaning treatment provides a better surface for bonding 2020-T6 unclad Al with AF-31 and Aerobond 422 adhesives than any of the other five surface treatments investigated. Test results also show that 2020-T6 unclad Al lap shear specimens bonded with AF-31 and Aerobond 422 adhesives possessed bond strengths comparable with 2024-T3 and 7075-T6 Al alloys bonded and tested under similar conditions.
