3621 Influence of DLC coating on the fatigue properties of Ti alloy
Details
Rotating bending fatigue tests had been performed in order to investigate the influence of DLC coating on the fatigue properties of Ti-6Al-4V Four types specimen coated by different coating time were prepared for the fatigue test. The result showed that fatigue limit and internal hardness improved as the coating time becomes longer. It is considered that this result was due to compressive residual stress generated on the specimen's surface during the process of the DLC coating.
