Study on Self Organization During Cutting Process of Coating Tools

Cutting experiments were performed using two types of multi-layer coating tools turning hardened 45 and T10A steel.SEM and XRD analysis were conducted on cutting tools.The results show that self organization exists during the cutting process of the coating tools.The formation,steady existence and disappearance of the self organization structure correspond respectively with the initial,normal and severe wear stage of the typical tribology process.The self organization mechanism is of great significance on the improvement of coating tool life.
