摘要

Tribological properties by two copper based composites (Micro-Cu-Al_2O_3 with grains size 1-2 11m and Nano-Cu-Al_2O_3 with grains size 100-200 nm) were studied by pin-on-disk technique against a steel ball at a range from room temperature up to 873 K. For both systems the coefficient of friction decreased between 473 K and 673 K by about 25 %. At lower temperatures the nano-Cu was about three times more wear resistant than the micro-Cu but the wear rate of both systems decreased down to zero at 673 K due to formation of hard oxide layers.
