Abstract

The behavior of surface layers of metals with a different lattice type (Cu, W, Ti) during friction is investigated in the present paper. The experiment by using synchrotron radiation diffractometry is carried out in the regime of simultaneous triboloading and high-sensitive diffraction pattern registration. It is determined that the dislocation structure as well as residual stresses of two kinds for commercially pure metals are unstable during friction and achieve the saturation level within the earliest 1-15 cycles of loading by the indenter. Changes in the dislocation structure are related to the dispersion of the deformation blocks and residual stresses of the first and second kind.
