含量越高,Al的扩散速率越低[18]. 图2 1 100 ℃条件下真空热处理5 h后涂层BSE截面形貌 Fig. 2 BSE images of cross-section of Ru/NiAlHf coated N5 alloy annealed at 1 100 ℃ for 5 h 表2 图2中界面下方不连续析出相化学成分 Table 2  ...防护技术.目前,热障涂层技术已成为先进涡轮叶片技术中与高效气冷技术,高温合金材料技术并重的三大关键科学技术之一[1-2]. NiAl合金因能在高温下形成连续致密的保护性氧化膜,成为理想的金属防护涂层和热障涂层粘结层材料.然而研究发现,NiAl涂层无法满足新一代含Re镍基单晶高温合金的要求,这是因为涂层中的Al原子向内扩散导致基体的γ/γ′相失稳,难熔元素析出,促进了二次反应区及有害拓扑密堆相的形成......

]. Because of their lower density as well as higher specific strength and stiffness compared with Al foam, Mg foam may have broader promising applications [5,6]. To date, several methods have been developed to prepare close-cell Mg foam, among which melt foaming process is more cost-effective and has been successfully applied to prepare Al foam [7,8]. In this method, blowing agent is added into the melt......
