摘要：在影响金刚石/金属基复合材料综合性能的众多因素中，界面被认为是影响复合材料力学性能和热物理性 能的关键因素。良好的界面结合不仅可保证两相间载荷的有效传递，更有助于减少因两相间存在的缺陷（如界面 生成物、孔隙、裂纹和脱粘等）而导致的非接触型热阻。W 热导率（178 W/mK）仅次于 Ag、Cu、Al，碳化后生成 的 WC 热导率较高（120 W/mK），并在金属基体中具有极低的溶解度，可最大程度满足低界面热阻的要求，被认 为是金刚石增强金属基复合材料界面改性层最理想的候选材料之一。本文从界面改性的角度综述了钨及其碳化物 在金属基复合材料界面改性的研究进展，并对未来高导热金属基复合材料的发展进行了展望。
