The XRD patterns of the magnesium alloy AZ91 after the treatment in reference solution of 0.05M Al(NO3)3∙9H2O + 0.25M NaNO3, and solution of sodium salts of salicylic acid, EDTA, NTA at pH 10.00 and T equal 95 °C during 6 h. The data are shifted vertically for clarity. The inset shows the Gaussian polynomial fit of NTA and EDTA patterns.
