Exfoliation Corrosion Testing of 7178 and 7075 Aluminum Alloys

Source

As special heat treatments to improve resistance of aluminum alloys to exfoliation were developed, the need for accelerated testing methods to control production heat treatment arose. A joint task group formed by ASTM Committee GO1.05 and the Aluminum Association has conducted an interlaboratory testing program of various salt spray and immersion tests for 7000 series alloys. A constant immersion test produced the best results.
