    摘要:

    采用陰極等離子體電沉積法制備了不同貴金屬摻雜氧化鋁涂層。結(jié)果表明,貴金屬摻雜氧化鋁制備的涂層孔隙率降低(特別是Al2O3-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,利用能斯特方程解釋了貴金屬和氧化鋁同時沉積的原因,對沉積的整個過程和機(jī)理進(jìn)行了分析和探討。

    Abstract:

    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.
