采用Ti-Ce,Ti-Al合金靶,利用电弧离子镀技术在高速钢基底上制备Ti-Al-Ce-N涂层,研究了Ce及Al对TiN系涂层的界面结合强度的影响,同时辅以显微硬度、抗氧化特性的测定,结合TiN涂层的组织结构,讨论了Al、Ce对TiN系涂层的改性。试验表明:TiN涂层中添加微量Ce和Al,可以明显改善膜基结合强度,并且有助于形成(111)和(222)择优取向,使膜层致密提高抗氧化能力。 The Ti-Al-Ce-N coatings were prepared on high-speed steel substrates by arc ion plating using Ti-Ce and Ti-Al alloy targets. The effects of Ce and Al on the interfacial bonding strength of TiN coatings were also studied. Supplemented by the determination of microhardness and oxidation resistance, combined with the microstructure of TiN coating, the modification of TiN coating by Al and Ce was discussed. Experiments show that adding trace amounts of Ce and Al to TiN coating can obviously improve the bonding strength of the film and help to form the preferential orientation of (111) and (222) and make the film dense to improve the anti-oxidation ability.
