| Abstract: | About the Influence of the Topography of the Steel Surface on Faults during Hot Galvanizing of Part Loads The topography of the steel surface can influence the formation of layers during hot galvanizing in many ways. Information is given on galvanizing faults caused by impressions in the steel surface (rolling and drawing ridges). Flux remainders accumulated in these impressions can be encapsulated in the zinc coating during hot galvanizing. This leads to cavities and pores in the coating or to sponge‐like zinc raisings at its surface. The flux remainders from the zinc coating can boil during powder coating and lead to blisters and pimple‐like rises in the coating. Therefore, steel surfaces designed for galvanizing should be even or only have flat impressions. |
