dc.description.abstractEffect of spraying time on the corrosion behaviour of uncoated and atmospheric plasma sprayed alumina (APS) coatings on AZ31B magnesium alloy in NaCl solutions of different spraying times, viz., 1 h, 4.5 h and 8 h has been examined. The corroded area was characterized by an optical microscope and X-ray diffraction. The results showed that the corrosion destruction of uncoated and coated samples was considerably affected by spraying time. The uncoated magnesium and alumina coatings were found to provide a better corrosion resistance in lower spraying time (1 h). However, the coatings and Mg alloy substrate were identified to be highly susceptible to localized damage, and could not provide an effective corrosion protection in higher spraying time (8 h). It was observed that the corrosion resistance of the ceramic coatings and base metal gets deteriorated with increasing the spraying times.en_US
