Microstructure and corrosion resistance of AM60 magnesium alloy modified by plasma surface treatment
Fine single solid solution α-Mg phases with an average grain size of less than 5 um was obtained in the melting layer of the surface of AM60 Mg alloy by means of plasma beam treatment. The influence of the plasma parameter on both the melting depth and the grain size was discussed. The microstructure, morphology and corrosion properties of the melting layer were analyzed by optical microscopy (OP), scanning electron microscopy (SEM), simulated corrosion test, respectively. The micro-hardness of the melting layer is up to 200 HV0.05 by means of environment-friendly plasma surface treatment and the corrosion resistance of AM60 magnesium alloy was greatly improved.
