Abstract
The surface treatment by tufftride effectively improves fatigue strength, resistance to corrosion and abrasion. This treatment is being used for many machine parts, but few studies on fatigue strength of tufftrided specimen have been made.
We have been conducting the experimental studies on fatigue behavior of tufftrided specimen since few years ago, and found many, experimental facts which have many problems to be studied. This paper describes some of the problems about the fatigue behavior of tufftrided specimen.
