Friction And Wear Properties

The friction and wear properties of an Al6061 alloy reinforced with carbon fibers (CF) modified with Cu-Ni bimetallic layers were researched. Cu-Ni double layers were applied to the CF by electroless plating and Al6061-matrix composites were prepared by powder metallurgy technology. The metal-CF/Al interfaces and post-dry-wear-testing wear loss weights, friction coefficients, worn surfaces, and wear debris were characterized. After T6 heat treatment, the interfacial bonding mechanism of Cu-Ni-CF changed from mechanical bonding to diffusion bonding and showed improved interfacial bonding strength because the Cu transition layer reduced the fiber damage caused by Ni diffusion. The metal–CF interfacial bonding strongly influenced the composite’s tribological properties. Compared to the Ni-CF/Al and Cu-CF/Al composites, the Cu-Ni-CF/Al composite showed the highest hardness, the lowest friction coefficient and wear rate, and the best load-carrying capacity. The wear mechanisms of Cu-Ni-CF/Al composite are mainly slight abrasive wear and adhesive wear.

The friction and wear properties of in situ Al-matrix composites prepared by selective laser melting (SLM) were evaluated on a ball-on-disk tribometer by sliding against GCr15 steel at room temperature. The influence of the applied load, sliding speed, and long-time continuous friction on the friction and wear properties of Al-matrix composites was systematically investigated. It showed that the wear rate and coefficient of friction (COF) increased when the applied load increased, due to the higher contact stress and larger extent of particle fracturing. As the sliding speed increased, the elevated rate of the formation of Al-oxide layer and the transfer of Fe-oxide layer from the counterface to the worn surface led to a significant reduction in wear rate and COF. As the sliding distance prolonged, the worn surface successively experienced the adhesive wear, the abrasive wear, the particle fracturing and crack nucleation, and the delaminated wear. The above processes were repeated on each exposed fresh surface, resulting in the fluctuation of COF. In the later stage of wear process, a large amount of oxides were produced on the worn surface, caused by the long-time accumulated frictional heat, which reduced the fluctuation of COF. The wear mechanisms of SLM-processed Al-matrix composite parts under various loads were dominated by abrasive wear and oxidation wear, whereas the predominant wear mechanisms were oxidation wear and delamination wear at different sliding speeds. For the long-time friction, all of these wear mechanisms were operational.
