| Résumé | High strength Al alloys used in aircraft structures are susceptible to stress corrosion cracking (SCC) in chloride containing environments. This paper outlines the work done to prevent SCC on 7075-T6 aluminum alloys as a function of the surface conditioning and with three different galvanic coatings. Coatings of pure Al, Al-Mg, and Al-Mg-Zn were applied by twin wire arc spraying and evaluated in 3.5 wt. % NaCl solution. Environment assisted cracking tests were performed using a four point loading set up under tensile fluctuating load at low frequency (0.1 Hz). Results indicate that shot peening is beneficial and SCC is inhibited by anodic thermal spray metallic coatings. |
