摘　　要：针对铝合金钻杆耐磨性和耐腐蚀性差导致其难以在深部钻井中应用的技术难题,本文以7075铝合金粉作为基体,玄武岩短纤维作为增强体,利用真空热压烧结技术制备了玄武岩纤维增强型铝基复合材料,并对其微观组织结构、密度和显微硬度等性能进行了研究。结果表明,玄武岩纤维在铝基体中分散均匀,界面处发生了化学渗透,SiO_2和Al之间发生置换反应,从而获得了良好的界面结合强度,复合材料的密实度较高,玄武岩纤维的加入显著提高了复合材料的显微硬度。In view of the difficulty in application of aluminum alloy drill pipes to deep drilling due to their poor wear resistance and corrosion resistance,the basalt fiber reinforced aluminum based composite material was prepared with the 7075 aluminum alloy powder as the base and basalt fibers as the reinforcement by vacuum hot pressing sintering technology.Study was conducted on its microstructure,density and micro⁃hardness,and the results showed that the basalt fiber is uniformly dispersed in the aluminum base,and substitution reaction takes place between SiO_2 and Al at the interface so as to obtain good interface bonding strength with higher density;meanwhile the addition of basalt fiber significantly improves the micro⁃hardness of the composite material.
