文摘

Since the use of hexavalent chromium in automotive and electronic equipment is largely prohibited, many different hexavalent chromium free conversion layers have been developed. In this work, different Cr-free phosphate and polycarboxylate based conversion coatings were characterized (with electron microscopy and other surface analytical methods) for the usage of a multifunctional property layer for hot dip galvanised steel strips. The different corrosion resistance of such conversion coatings on ZM (ZnAlMg) and Z (Zn) will be another topic of this paper. The corrosion protection properties of these phosphate based conversion coatings on Z and ZM were characterized in a standardized salt spray test. Finally the conversion layers and the barrier protection effect on Cr-free treated zinc and zinc magnesium was investigated by cyclovoltammetry.
