Effect of Copper Additives on Mechanical and Tribotechnical Properties of Sintered Composites Al-Sn

Abstract:

The mechanical and tribotechnical properties of sintered composites Al-Sn with small copper additives were studied. The sintering of compacts of pure metal powders mixture conducted in the vacuum furnace. It was established that copper additions up to 2% (wt.) lead to a significant increase in the strength and sharp decrease in a plasticity of Al-Sn composites. Because last, only Al-20Sn-1Cu alloy samples saved the integrity under the multiple equal channels angular pressing. The strength of treated samples significantly increased, but their compressive deformation did not exceed 0.5%. The wear intensity of Al-Sn-Cu samples under the dry friction was higher in comparison with Al-Sn composites.
