Abstract

B₄C_p/2024Al composite with volume fraction of 45% was designed and fabricated by pressure infiltration technology. Microstructure and friction and wear properties of B₄C_p/2024Al composites were studied. The results show that reinforcement particles are uniformly distributed and a qualified relative density of the composite has been achieved. A high density of dislocations was observed to be in the peripheral area of the reinforcement particles, and a large number of fine acicular precipitates were found. Coefficient of friction of B₄C_p/2024Al composites decreased slightly with increasing load and sliding speed, meanwhile, the wear rate increased with increasing load and sliding speed. Main forms of wear in B₄C_p/2024Al composites were abrasive wear, adhesive wear and oxidation wear.
