摘要： 为研究合金化热镀锌产品镀层抗粉化性能,通过辉光放电光谱仪(GDS 750A)测量、X射线衍射(XRD)、扫描电镜(SEM S4200)观察等手段对不同合金化热镀锌高强IF钢的镀层厚度、镀层铁含量、镀层铝含量和镀层相结构等进行了研究·结果表明:对于所研究的合金化热镀锌高强IF钢,镀层较厚、镀层铝含量低时镀层的粉化量较大;当镀层表面和次表面是以疏松的δ1相为主的相结构时,镀层抗粉化性能明显好于镀层表面以致密的粒状δ1相为主的相结构·

Abstract: To investigate coating powdering resistance of galvannealed steel, coating thickness, coating Fe content, coaling Al content and coating phase distribution of different galvannealed high strength IF steels were investigated with glow discharge spectrometer (GDS-750A), X-ray diffraction (XRD) and scanning electron microscope (SEM-S4200). It was indicated that for the investigated galvannealed high strength IF steel when the coating thickness was high and the coating Al content was low, the coating powdering quantity was larger. It was also indicated that when the surface coating and sub-surface coating were mainly composed of loose δ1 phase, the coating powdering resistance was much better than that of coating with almost all of compact particulate δ1 phase in the surface coating.
