Abstract:

Test panels of 0.125 in. x 6 in. x 6 in. bare 7075T6 aluminum alloy sheet were coated with a 19 mil thickness of Albi 99, a 20 mil thickness of Thermo-Clad No. 94HAl, or a 20 mil thickness Duo-Tex. After curing, these coatings were impinged upon with a gas-oxygen flame regulated to produce a 2100 F impingement temperature for ten minutes, and with a hydrogen burner flame adjusted to produce an impingement gas stream at 750 F and about 100 psi pressure for 10 minutes. The coatings were eroded away by the velocity of the impinging gas streams representative of flight operating conditions. Author
