Ni含量对Cu-xNi-35Fe/8Gr耐磨材料性能的影响
Effect of Ni content on the performance of Cu-xNi-35Fe/8Gr wear resistant materials
摘要
Abstract
The present study investigated the influence of Ni content on the microstructural characteristics,mechanical properties,and tribological behavior of copper matrix graphite composites(Cu-Ni-35Fe/8Gr).With the addition of 0～25%Ni by mass fraction,the microstructures of Cu-Ni-35Fe/8Gr exhibited a homogeneous distribution.As the Ni content increased from 0%to 15%,a significant enhancement in hardness from 59 HB to 70 HB,tensile strength from 81 MPa to 101 MPa,and bending strength from 161 MPa to 220 MPa was observed.The addition of Ni also improved the friction and wear properties of the material,reducing the dry friction coefficient by 10%to 0.18 and the wear rate from 16 mg/h to 7 mg/h.The findings suggest that incorporating an appropriate Ni content can effectively improve the comprehensive mechanical properties,reduce the friction coefficient,facilitate the formation of a smooth and stable friction surface,and mitigate adhesive wear,consequently enhancing the overall performance of Cu-Ni-35Fe/8Gr composites.关键词
