This paper deals with the study of crystallization and phase transformation Ni-P coatings deposited on AZ91 magnesium alloy. Prepared samples were characterized in terms surface morphology elemental composition by means scanning electron microscopy energy-dispersive spectroscopy analysis. The results X-ray diffraction analysis differential calorimetry suggested that increasing phosphorus conten...

Superhydrophobic surfaces were prepared using a two-step method that involved the etching of AZ31 and AZ91 magnesium alloys then modifying etched with stearic acid. Magnesium ZnCl2 SnCl2 exhibited roughened micro- nanoscale hierarchical structures consisting two chemically distinct regions (Zn/Zn(OH)2 or Sn/SnO2 Mg(OH)2). An optimum time ten minutes was chosen for both etchants. highest contact...

Due to their good properties, including biodegradability and similar characteristics natural bone, magnesium alloys have potential applications in implant manufacturing for biomedicine orthopedics.In this study, chitosan or/and hydroxyapatite layers were performed on the surface of AZ91 alloy using electrophoretic deposition process. The microstructure coating, mechanical hydrogen evolution, pH...
