采用扫描电子显微镜、电子探针等分析无铅建筑铝搪瓷界面的显微结构和元素分布,并结合铝搪瓷的密着强度,探讨了无铅建筑铝搪瓷的密着机理。结果表明,密着性能优良的无铅建筑铝搪瓷面存在铝元素与瓷釉元素相互扩散的中间过渡层;中间过渡层与金属铝的结合主要通过金属键来实现,中间过渡层与瓷釉层的结合主要是通过离子键和共价键来实现。 相似文献

The microchemistry of steel/enamel interfaces was investigated, on a nearly atomic scale, by means of X-ray photoelectron spectroscopy. Experimental evidence is given that good adherence is characterized by a fully reacted iron silicate phase, which produces a local chemical continuity between steel and enamel, whereas bad adherence is associated with a heterogeneous mixture of an iron silicate phase plus unreacted FeO. 相似文献
