论文摘要
使用各种高级显微镜和光谱技术检查了钢合金元素对热浸镀锌压力镀锌钢的表面氧化层的影响。原始薄AL2O3层顶部的主要氧化物源自主要的镀锌过程，被鉴定为ZnO和（Mn，Zn）MN2O4尖晶石。对于某些研究的钢合金（一种不均匀的钢合金），在Al2O3层上发现了额外的薄膜。在足够高的浓度下，CR可以用CR2O3在退火，增强和再生原始Al2O3层的过程中代替Al。使用二级离子质谱法进行进一步分析，允许ZnO和Zn（OH）2之间的可靠区别。
Effects of steel alloying elements on the formation of the surface oxide layer of hot-dip galvanized press hardened steel after austenitization annealing were examined with various advanced microscopy and spectroscopy techniques. The main oxides on top of the original thin Al2O3 layer, originating from the primary galvanizing process, are identified as ZnO and (Mn,Zn)Mn2O4 spinel. For some of the investigated steel alloys, a non-uniform, several nanometer thick Cr enriched, additional film was found at the Al2O3 layer. At a sufficiently high concentration, Cr can act as a substitute for Al during annealing, strengthening and regenerating the original Al2O3 layer with Cr2O3. Further analysis with secondary ion mass spectrometry allowed a reliable distinction between ZnO and Zn(OH)2.
