Analysis of Structural Transformations Occuring in Surface Layers of D16 Alloy Samples During Sliding Friction

Аннотация

The method of diffractometry based on the use of synchrotron radiation was used to study the structural transformations occurring in the surface layers of the D16 alloy samples in the course of sliding friction. Information on the defect structure of materials at each sample rotation was obtained in real time. Under the conditions of dry sliding friction, intensive defect accumulation occurs at the initial stage of loading and then the wear process reaches the stable level. Further on, the shape of X-ray line profiles stabilizes, which indicates the equilibrium of competing processes of defect accumulation and relaxation of emerging stresses.
