In this study, the applicability of hydroxyapatite (HA) coatings on Al-Cu-Mg alloys (Al2024) was investigated by electrochemical techniques. The structural characterizations coated layers were SEM, EDS, and XRD equipment. surface adhesion resistance degradation behavior tested scratch potentiodynamic scanning (PDS) tests, respectively. It observed that HA coating had a homogeneous structure Al2...
