2O3-Ru），涂層的耐高溫循環(huán)氧化性能和抗剝落性能均有所提升。Al2O3-Ru復(fù)合涂層的效果更好，平均氧化速率值K和平均氧化物碎裂量G最小。同時(shí)，利用能斯特方程解釋了貴金屬和氧化鋁同時(shí)沉積的原因，對沉積的整個(gè)過程和機(jī)理進(jìn)行了分析和探討。;Alumina coatings doped with different precious metals were prepared by cathode plasma electrolytic deposition. Results show that the porosity of precious metal-doped alumina coatings (especially Al2O3-Ru) decreases, and the high-temperature cyclic oxidation resistance and spallation resistance are enhanced. The Al2O3-Ru composite coating shows better effect: its average oxidation rate K and average amount of oxide spallation G are minimum. Meanwhile, Nernst equation was used to explain the simultaneous deposition of precious metal and alumina, and the whole process and mechanism of deposition were analyzed."/>
