="ChDivSummary" name="ChDivSummary">An l-cysteine-bioinspired calcium phosphate(Ca-P) coating is prepared upon magnesium alloy AZ31 in a water bath at 60?C. FE–SEM, FTIR, XRD, electrochemical characterization, hydrogen evolution tests and XPS were used to evaluate the microstructure, chemistry and corrosion performance of the samples.Results indicate that l-cysteine promotes the nucleation process......
