中国科学院兰州化学物理研究所的研究人员利用热喷涂技术制备了一种微/纳双尺寸硬质颗粒增强的CoCrAlY基复合涂层。其不仅力学性能优异,与底材结合牢固,而且抗高温氧化性能突出,热重分析表明,其室温到1000℃的氧化增重低于1mg/cm~2。 Researchers at the Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, have prepared a CoCrAlY-based composite coating with micro / nano double-size hard particles reinforced by thermal spraying. It not only has excellent mechanical properties and firm bonding with the substrate, but also has high resistance to high temperature oxidation. The thermogravimetric analysis shows that the oxidation weight gain from room temperature to 1000 ℃ is lower than 1mg / cm ~ 2.
