摘要：本论文是采用阳极氧化铝膜为载体，然后用电镀的方法制备了Cu-Ni-Al2O3复合膜、Cu-Ni-La-Al2O3复合膜和Cu-Ni-Er-Al2O3复合膜。将这些复合膜分别在300℃、500℃、600℃、700℃、800℃、900℃下进行热处理，退火时间为2h，采用电子能谱仪(EDX)、电子扫描显微镜(SEM)和X射线衍射仪(XRD)的方法表征经过不同温度热处理的Cu-Ni-Al2O3、Cu-Ni-La-Al2O3、Cu-Ni-Er-Al2O3复合膜的组成成分、微观形貌、晶型结构。结果表明，通过电子能谱图分析可知，我们制作的是Cu-Ni-Al2O3复合膜、Cu-Ni-La-Al2O3复合膜和Cu-Ni-Er-Al2O3复合膜。Cu-Ni-La-Al2O3复合膜的最平整微观形貌也是3个复合膜中最为平整的。Cu-Ni-Al2O3复合膜铜的相对含量随着温度的升高逐渐减小，镍的相对含量随着温度的升高逐渐增大。而Cu-Ni-Er/Al2O3复合膜镍的含量，整体上看，随着温度的升高镍的含量逐渐增加。通过对晶型结构的分析，Cu-Ni- Er/Al2O3复合膜与Cu-Ni-La/Al2O3复合膜相同在退火温度为25℃~900℃期间为Cu3.8Ni晶型结构，在退火温度800℃的时候复合膜出现向氧化铝晶型的转变，在退火温度为900℃的时候氧化铝转化成晶型结构，复合膜为Cu3.8Ni晶型和氧化铝晶型共存。19512

The study of performance of Cu-Ni- (La、Er)-Al2O3 composite membrane
Abstract: This article used anodic alumina membranes as a carrier, then plating method for preparing Cu-Ni-Al2O3 composite membrane, Cu-Ni-La-Al2O3 composite membrane and Cu-Ni-Er-Al2O3 composite membrane. Handled a heat treatment with the processed composite membrane at 300 ℃, 500 ℃, 600 ℃, 700 ℃, 800 ℃, 900 ℃,and the annealing time was 2h, then used the methods with electron spectroscopy (EDX), scanning electron microscopy (SEM) and X -ray diffraction (XRD) to characterize the microstructure, the composition and crystalline structure of Cu-Ni-Al2O3 composite membrane, Cu-Ni-La-Al2O3 composite membrane, Cu-Ni-Er-Al2O3 composite membrane composition through different temperature of the heat treatment. The results showed that by electron spectroscopy map analysis, we have produced is indeed Cu-Ni-Al2O3 composite films, Cu-Ni-La-Al2O3 composite films and Cu-Ni-Er-Al2O3 composite film. And most flat morphology Cu-Ni-La-Al2O3 composite membrane is most flat. The relative content of Cu-Ni-Al2O3 composite membrane of copper decreases with increasing temperature, and the relative content of nickel increases with increasing temperature. The nickel content of the Cu-Ni-Er/Al2O3 composite film, on the whole, with the temperature gradually increased nickel content increases. Through the analysis of the crystal structure, Cu-Ni-Er/Al2O3 and Cu-Ni-La/Al2O3 composite membrane and a composite membrane in the same period of the annealing temperature is 25 ℃~900 ℃ Cu3.8Ni crystal structure, the annealing temperature of 800 when the appearance of the composite film crystalline transition alumina, an alumina crystal structure into the composite film is a crystalline alumina Cu3.8Ni coexisting polymorph annealing time at 900 ℃.
