【摘要】 本文介绍用一种蒸镀的方法在碳化硼颗粒（B₄C_p）表面涂覆一层含钛金属的涂层,使得金属基复合材料的B₄C_p-Me体系中的界面结合强度得到改善。X射线衍射分析表明,经涂覆后B₄C_p表面的结构组成由内向外依次为B₄C→TiB₂→TiN.差热分析也证实了涂覆后的B₄C_p表面产生新的物相,热重分析表明经涂覆后的B₄C_p的热稳定性较未涂覆的高。磨损实验表明,使用经过涂覆的颗粒所制备的复合材料具有更高的耐磨性,这是一种简单实用的评价B₄C_p-Me复合材料体系界面结合强度的方法。更多还原

【Abstract】 The method of vaporizing plating by which the containing titanium metal coating was coated on surface of B4C particles was introduced.It is the purpose improving integrating intensity of interface of B4Cp/Me.The X ray diffraction analysis indicate that the structure form of surface of B4CP after coating is B4C→TiB2→TiN in turn from inner to outer.And Differential Thermal Analysis (DTA) substantiate that the new phase appears on the surface of B4CP after coating.And Thermogravimetry Analysis (TGA) show that the thermal stability of B4CP after coating is higher than that before coating.The wear experiment is simple and applied method evaluating integrating intensity of interface of B4Cp/Me更多还原
