Four kinds of mating materials,45 steel,beryllium bronze,beryllium bronze modified by silicon carbide particles,alumina coating were prepared,and their effects on the tribological properties of a resin based friction material were investigated by MM1000 II friction tester under the dry condition.The worn surface morphology was analyzed by polarizing microscope.The experimental results show that the mating material of alumina coating has the minimum wear rate and moderate friction coefficient,but bad friction coefficient stability.The mating material of 45 steel has low friction coefficient but the best friction coefficient stability.The mating material of beryllium bronze has the best friction and wear properties,such as higher and more stable friction coefficient.Both the mating material of beryllium bronze and friction material have low wear rate,and there are no holes and furrows on the surface of beryllium bronze.Beryllium bronze modified by silicon carbide particles shows a poor performance in every respect.
