Tribo-metallographic behavior of high carbon steels in dry sliding III. Dynamic microstructural changes and wear

The wear micromechanisms of various microstructures in 52100 and 1080 steel s were studied, using scanning electron microscopy, transmission electron m icroscopy, X-ray diffraction and microhardness indentation. The results sho w that the difference in wear resistance of various microstructures depends not only on differences in microstructural thermal stability, resistance t o plastic deformation, resistance to initiation and propagation of microcra cks, especially, but also on the dynamic changes of different microstructur es and the difference in energy consumption in wear surface layers during s liding.
