Abstract

In this study, the effect of flush grinding process on the corrosion fatigue behavior of step heat treated 7020 aluminum alloys was investigated. Corrosive fatigue tests were performed with a plane bending device in an atmospheric environment and in a corrosive environment provided by fresh sea water brought from the Black Sea. While performing fatigue tests, the stress ratio was taken as R = 0. In the experimental study, it was observed that the fatigue strength of both the two-step aged samples and the two-step aged + flush grinding treated samples in the atmospheric environment was better than in the corrosion environment. It was observed that the flush grinding process had no improving effect on the corrosion fatigue properties of the samples subjected to the two-step aging.
