Abstract

In order to achieve thermally sprayed steel which indicate higher fatigue properties, ettective fusing methods were performed by using both an induction heating system and a vacuum furnace. In our previous studies, fusing by an induction heating system can form the sprayed coating which was prevented segregation of chromium compound, and fusing by a vacuum furnace can form the thicker diffusion layer which indicates higher adhesive strength. Method of performing pre-heating by a vacuum furnace before fusing by an induction heating system couldn't achieve thermally sprayed steel which indicate higher fatigue properties because delamination between the coating layer and substrate was occurred. However, method of performing re-heating by a vacuum furnace after fusing by an induction heating system could. As the result, thermally sprayed steel indicate 300% higher fatigue strength compare with substrate only.
