Original Abstract

The effect of plasma electrolytic oxidation (PEO) on the fatigue of AZ61 magnesium alloy has been investigated under high cycle conditions in air and 3.5% NaCl solution. PEOemployed an alkaline pyrophosphate-silicate-fluoride electrolyte, with an offset square waveform, a frequency of 50 Hz, and current density of 130 mA cm-2.The PEO treatment led to reductions in the fatigue limit by 38% in air and by 56% in 3.5% NaCl solution. The reduction of the fatigue limit is attributed to cracking of the coating, roughness of the alloy/coating interface, corrosion and influences of Al-Mn particles.
