Abstract:
A friction material comprising a Fe part; a coating layer formed over a surface of the Fe part; and a friction part formed on a surface of at least a part of the coating layer wherein: the coating layer comprises a first coating layer and a second coating layer in order from Fe part side, the first coating layer is constituted of an alloy containing Cu, Ni and Fe such that Fe content be not less than 10 atom %, the second coating layer is constituted of an alloy containing Cu and Ni, or an alloy containing Cu, Ni and Fe such that Fe content be less than 10 atom %, an average thickness of the first coating layer is not less than 1.0 μm and not more than 6.0 μm; and an average thickness of the second coating layer is not less than 9.5 μm and not more than 24.0 μm.
