7. Calculate the oxide-to-metal volume (Pilling-Bedworth) ratios for the oxidation of the metals listed in the table below, and comment on whether their oxides might be protective or not. MetalOx...
Suggest and describe a process that can be used to artificially build up the protective oxide layer on the surface of aluminium. Describe one benefit of this process (other than corrosion protection) Two uncoated 70/30 brass plates are joined together using a 70/30 brass bolt. A small overlap area results. Suggest one possible type of corrosion the design may suffer from and describe the corrosion mechanism. Propose an improvement to the design to eliminate the risk of corrosion A welded...
