The bronze based composite reinforced with Ni3Al particles was produced by classical powder metallurgy (PM) technique. Particles used as reinforcement were produced via ball milling of Ni3Al cast alloy. The powders of constituents of bronze and Ni3Al powder (1%wt.75-100 mu m particle in size) were mixed, compacted axially and sintered. The composite was characterized using light microscopy and scanning electron microscopy. The compression strength and hardness of composites were determined. The tribological properties of composite and unreinforced bronze were determined at pin-on-disc geometry and results were compared with conventional phenolic resin bonded brake lining. The results revealed that PM bronze has higher strength than composite. The hardness of composite is higher than PM bronze. The sliding and wear tests revealed that the wear resistance and coefficient of friction of composite are higher than conventional brake lining.
