EFFECTS OF Al2O3 PARTICLE SIZE AND CONTENT ON PROPERTIES OF α-Al2O3/Cu COMPOSITE COATING

  • The properties and wear characteristic of Al2O3 particles reinforced copper composite by electrodeposit have been investigated, and their hardness and wearability were tested in the range of 0.5 to 5.0μm particles size and 4 to 16vol% content. The results show that the coating hardness increases linearly with Al2O3 content, and the coating with large Al2O3 particles is slightly harder than the one with smaller particles. The content and the size of Al2O3 particles have great effects on the wearability and wear mechanism of the composites.
