into composite under constant loads are fractured by the tangential frictional forces after a long time. There are some wear debris (shown in Fig.7) in the form of particle chips generated along the periphery... to the tangential frictional forces, which get rise to flying increase of wear loss rate. Consequently, as the thickness of reaction layer is controlled under a critical value, composites reinforced by coarse WC......
). Seen from Fig.11(a), the wear scar of the no RE-coating is narrower than that of P110 steel. Some cracks and delaminations are evident in Fig.11(b). Studies show that the contact between the frictional...J. Cent. South Univ. Technol.
