摘　　要：研究了纯铜表面双层辉光离子渗钛合金层及纯铜在空气中的高温氧化行为,用X射线衍射仪(XRD)分析氧化层的相组成并讨论了氧化机理.结果表明:纯铜渗钛后不仅提高了抗氧化能力,而且氧化行为及氧化层的结构也发生了变化.未渗钛的纯铜70 0℃氧化10 0h相组成为Cu2 O和CuO ,而Cu -Ti合金层主要为致密均匀的TiO2 氧化层.The oxidation behavior of pure copper and Cu-Ti alloy layer made by double glow discharge process were investigated in air at 400℃～700℃.The formed oxide scales were examined by XRD,and the oxidation mechanism was discussed.The results indicated that the oxidation resistance of Cu is significantly improved by titanizing treatment.After oxidation at 700℃ for 100?h,the formed oxide scale on pure copper consists of Cu 2O,CuO and that on titanized Cu is mainly composed of TiO 2.The oxidation kinetic curves follow parabolic rate law.
