用俄歇(Auger)电子扫描微观分析法,X-光光电子谱仪,氩离子溅射剥层法等最新发展的方法结合电镜、X-光分析,前人曾观察到Ni-20Cr合金在氧化和还原的气氛中形成的表面层结构。它包括有NiO,NiCr_2O_4,Cr_2O_3、α-Al_2O_3四种氧化物。作者根据这些氧化物的晶体结构和Ni、Cr实验原子磁矩数,应用作者所发展的经验电子理论得到的NiO的高、低温相,Cr_2O_3、α-Al_2O_3的详细价电子结构以及NiCr_2O_4的同型尖晶石型结构如Fe_3O_4、NiFe_2O_4………所共有的价电子结构的一般结果,对氧化层特别对还原层的表面层结构进行了价电子键结合深度的分析。很简单而自然地说明了这种表面固体化学的实验。
With Auger electron microscopic analysis, X-ray photoelectron spectroscopy, argon ion sputtering stripping methods such as the latest development combined with electron microscopy, X-ray analysis, we have observed Ni-20Cr alloy oxidation And the surface layer structure formed in the atmosphere of reduction. It includes NiO, NiCr_2O_4, Cr_2O_3, α-Al_2O_3 four oxides. Based on the crystal structures of these oxides and the magnetic moments of Ni and Cr experimental atoms, the authors obtained the detailed valence electron structures of NiO high and low temperature phases, Cr 2 O 3 and α-Al 2 O 3 as well as the homogeneous tip of NiCr 2 O 4 using the empirical electron theory developed by the authors The general result of the valence electron structure shared by the spinel structure such as Fe 3 O 4 and NiFe 2 O 4 shows that the surface layer structure of oxide layer, especially reduction layer, is analyzed by the valence electron bonding depth. This simple solid experiment of surface solid chemistry is very simple and natural.
