摘要：basalt fibers/7075 aluminum matrix composites were studied to meet the demand of aluminum alloy drill pipes for material wear *** composites with different basalt fiber additions were prepared by hot pressed sintering and hot *** mechanical properties as well as friction and wear properties of the composites were studied by microstructure analysis,tensile experiments,friction and wear *** results showed that basalt fibers were oriented and uniformly distributed and led to local grain refinement in the alloy *** hardness and elongation of the composites were *** friction coefficient of the composites increased and then decreased,and the maximum wear depth and wear amount decreased,then increased,then decreased again with the growth of basalt fiber ***,the inclusion of basalt fibers mitigated the uneven wear of the extruded 7075 aluminum *** value of wear depth difference of 7075-0.2BF was the smallest,and that of 7075-2.0BF was close to *** maximum wear depth and wear volume the 7075-0.2BF and 7075-2.0BF were also the *** inhibition of uneven wear by basalt fibers enhanced of wear resistance for 7075 aluminum alloy,which has reference significance for improving the performance of aluminum alloy drill pipes.
