Composite zinc-fly ash coating on mild steel

The corrosion was one of the most crucial issues which mankind has been faced. Corrosion naturally impacts our daily life trough chemical reactions that occur on the surface of metal and will impair the function of metal. In addition, the production of waste fly ash from a thermal power plant shows...
