Secondary ion mass spectrometry with a Cameca ion microscope was used to study the surface and in‐depth composition of a 55 wt % AlZn coating on steel wire. Several surface contaminants of the coating (C, Na, Mg, F, Cl, K, Ca, Mn and Fe) were identified and the spatial distribution of some of them and of the coating components Al, Si and Zn were obtained. The dendritic–interdendritic structure of the AlZn coating was observed using a secondary ion imaging facility. The distribution at the surface of the coating constituents Na and Cl, C and Al and Mn and Fe were strongly correlated. Quantitative analysis showed that the Mn and Fe surface concentrations were some hundreds and some thousand p.p.m. wt, respectively.
