| 摘 要： | 用俄歇谱仪对真空热处理条件下镍基高温合金的表面成分进行分析,利用润湿测量系统研究了Ni-15Cr-3.5B合金熔体在镍基合金基片上的润湿行为。结果表明,镍基高温合金基片表面有一层氧化铝膜,该氧化膜在真空加热时的厚度增加;Ni-15Cr-3.5B熔态合金润湿镍基合金基片时,氧化膜开裂,熔化的合金渗过裂缝,在氧化膜下铺展,具有良好的润湿性。

| Abstract: | The surface compositions of Ni-base superalloy under vacuum heat treatment were investigated by AES.The wetting behavior of molten Ni-15Cr-3.5B alloy on the superalloy substrate was studied by the measuring apparatus of wetting ability.The results show that the aluminum oxide film is formed on the surface of Ni-base superalloy substrate and the thickness of the film increases with the increase of the temperature of vacuum heat treatment.During wetting process,the oxidation film of the Ni-base substrate surface splits,then the molten alloy soaks through the cracks and spreads below the oxidation film.The wetting ability of molten alloy on the substrate is good. |
