【摘要】 在活性氧流动介质和干空气中,用高频感应氧化工艺在M5锆合金表面生成氧化锆陶瓷膜进行了研究。对处理温度、处理介质和处理时间等因素对氧化锆陶瓷膜生长速度、显微硬度以及耐腐蚀性能的影响进行了测试及分析。研究表明,在合适的温度范围,在高活性氧流动介质中,处理3-20 min可获得耐腐蚀性能优良的硬质陶瓷膜。更多还原

【Abstract】 It is researched the preparation of ceramic layer on the surface of M5 zirconium alloy by high-frequency induction oxidation process in active flow oxygen medium and in dry air. The corrosion resistance, thickness and microhardness of layers formed under different treating temperatures, treating media and treating times, were tested and analyzed. The results showed that after treating in active flow oxygen medium of a suitable tempereture for 3 minutes to 20 minutes, a hard ceramic layer with excellent corrosion resistance could be obtained.更多还原
