Abstract
A method of manufacturing an aluminum-base composite disc rotor comprising the steps of preparing a rough-shaped disc rotor made of a mixture of aluminum powder or aluminum alloy powder with reinforcing particles or aluminum alloy, placing a mixture of aluminum powder or aluminum alloy powder with reinforcing particles or a preform made thereof on each of fixed positions of the rough-shaped disc rotor, and heating the mixture or the preform to at least a region of mashy state temperature to mold under pressure. Thereby the heat resistance and the wear resistance of the aluminum-base composite disc rotor for light-duty cars and industrial machinery are improved.
