Effect of solution and aging treatment on microstructure and hardness of aluminum bronze

Abstract Due to their excellent corrosion resistance and wear resistance, bearing bushes made of aluminium bronze are widely used in pumps, heavy equipment marine equipment. Aluminium is also valve for tank improve defence. This work aims enhance the hardness QAl10-3-1.5 extruded by performing heat treatment at different solution temperature, quenchant, aging temperature. The results show that when aluminum content raw material more than 9.4%, after obtain a significant enhancement hardness. value can reach above 207HB, which meets design requirements drawings improves resistance.
