Abstract Scope |
Formation of multi-layers coating formed as a result of thermal diffusion induced galvanizing of steel in a fluidized Zinc bed powder layer has been investigated by means of optical and scanning electron microscopy. It was found that the microstructure of the formed layers correspond to the literature reported results. Some Zn amount was found in the neighboring layer in the steel substrate, which is an evidence for diffusion bonding between the formed Zn-rich coating and steel substrate occurred. The chemical composition of this zone corresponds to alpha-Fe(Zn) phase. Zn-rich thermal diffusion built coating consists of two intermetallic compounds, namely: FeZn10 and Fe3Zn10. The process parameters effect on the coating's formation (powders blend composition and pre-process treatment, fluidization time and temperature, carrier gas flow rate, surface preparation, etc.) have been examined and optimized. |
