利用扫描俄歇微探针测量了金属玻璃GB43(Fe_(78·48) Sl_(4·99) B_(16·53))的表面及深度方向的元素分布,考查了淬火状态和真空退火态以及自由面和辊面的差别。结果表明,表面氧化膜的厚度对同一状态的试样,辊面氧化膜比自由面的厚,同时其组成在自由面主要为SiO_2,而在辊面则为B和Si的混合氧化物,并且随退火温度增加,B的氧化物比重也增加、Si的氧化物比重减少。氧化膜厚度随退火温度增加而减少,同时B氧化层向试样表面移动。在400℃退火时,Fe的氧化加强。表面杂质分析看到,试样表面均有C、S、Ca、N、K等吸附元素,辊面有Cu,真空热处理可以消除部分表面吸附的杂质元素。
The elemental distribution in the surface and in the depth direction of GB43 (Fe_ (78.48) S_4.99B_ (16.53)) was measured by scanning Auger microprobe. The quenched state and vacuum annealed state were investigated. The difference between free surface and roller surface. The results show that the thickness of the oxide film on the surface is thicker than the free surface of the oxide film on the roller surface in the same state, and the composition is composed mainly of SiO2 on the free surface and mixed oxide of B and Si on the roller surface. As the annealing temperature increases, the oxide specific gravity of B also increases, and the oxide specific gravity of Si decreases. The thickness of the oxide film decreases with increasing annealing temperature, and the B oxide layer moves toward the sample surface. The oxidation of Fe is enhanced when annealed at 400 ° C. Surface impurity analysis shows that there are C, S, Ca, N, K and other adsorption elements on the sample surface and Cu on the roll surface. The vacuum heat treatment can eliminate some of the impurity elements adsorbed on the surface.
