  4. Abstract:
  5. Hydrothermal method was applied to create a protective coating on the Mg–4Zn–0.3Sr alloy, using de-ionized water (as precursor) for different synthesizing times of 3, 4, 5, and 6 h. XRD and EDS line-scan confirmed formation of Mg(OH)2 coating. Based on the surface morphological appearance, 5 h coating time at 160 °C was found to be the optimum condition. The corrosion current of 2.58 µA/cm2 in the uncoated sample decreased to 0.48 µA/cm2 in the coated condition. Also, the cytotoxicity assessments using Alamar blue test showed that the cell viability and cell attachment to the formed Mg(OH)2 coating are more pronounced in comparison with the uncoated alloy. © 2022 Elsevier B.V
