Thermal explosion reaction synthetic coating on diamond surface

  • 摘要: 以M(Mn或Cr)/Al/B/Diamond粉体为原料,通过热爆反应技术在金刚石表面生成多元复合涂层,并用X射线衍射仪、扫描电镜结合能谱仪研究2种原料体系及不同Al含量对陶瓷基体和涂层的物相组成和显微形貌的影响。结果表明:在N2的保护和引爆下,Cr/Al/B/Diamond粉体的热爆反应在金刚石表面形成CrB-AlN基多元复合涂层及Cr5Al8和Cr2AlB2等副产物;在Ar保护下,Mn/Al/B/Diamond粉体的热爆反应在金刚石表面形成Mn2AlB2基复合涂层。2种涂层对金刚石的包裹良好。2种热爆反应由于放热量较小,反应产物难以烧结成块体。制备出的疏松多孔块体易于粉碎和分离,从而可将陶瓷基体与金刚石颗粒分离。
