Fig. 2

Density estimated using Gaussian kernel density estimation. This figure shows the correlation between elemental content (in atomic percent, a.t. %) and corrosion resistance (represented by the logarithm of the corrected current, ln(I_corr)). Each panel presents a scatter plot for a specific element (Al, Fe, Co, Ni, Cr, Cu, Mn), with the x-axis corresponding to the elemental content and the y-axis to the logarithm of the corrosion current. A linear regression line is included to indicate the trend of the correlation. The color density, estimated using Gaussian kernel density estimation, represents the concentration of data points at specific locations within each plot. Correlation coefficients are displayed in each panel.
