WebbPolymers show wear processes that are different from that of metals. There are not only abrasive processes with powder-like wear debris but also adhesive processes with the creation of transfer layers which may be smooth or rough. Also ploughing wear and melting or plastic deformation is possible. WebbThe depth of the wear grooves caused by ploughing wear decreased with increasing CNT content, suggesting that the strengthening effects of nanotubes increased the wear resistance of aluminum alloy-CNT nanocomposite.
