•Very high cycle fretting fatigue tests with mean stress were successfully performed by ultrasonic fatigue system.•Fretting reduced the material’s fatigue strength when compared to plain fatigue, and further reduced by the effect of mean stress.•The main damage in fretting fatigue was delamination w...
