Abstract:Based upon considering the comprehensive properties of the aluminium-bronze and judging by the design principles of the micro-structure of the aluminium-bronze, a new high-strength and wear-resistance aluminium-bronze has been developed; its structures, properties, and tribological characteristics were discussed thoroughly and compared with those of the similar alloys at home and abroad. The results showed that the newly developed aluminium-bronze is superior to other similar alloys in mechanical properties and friction-wear behaviours, showing the characteristics of a kind of excellent wear-resistant material for engineering uses.
