  • A study on biocompatibility of gadolinium based anodizing coating AZ91D magnesium alloy in Simulated Body Fluid (SBF) solution 

    Farah Alina, Ab. Aziz; Siti Norbahiyah, Mohamad Badari; Mohd Zamzuri, Mohammad Zain (Trans Tech Publications, 2014-06)
    Pure Mg and AZ91D alloy was anodized with and without the gadolinium nitrate Gd(NO3)3 in different concentrations (0.001g/l, 0.025g/l, 0.05g/l, 0.075g/l and 0.09g/l) at a constant current density and treatment time of ...
  • Characterization of oxide film by vanadium based anodic oxidation coating 

    Mohd Zamzuri, Mohammad Zain; Nor Fadzilah, Toha; Siti Norbahiyah Mohamad Badari (Trans Tech Publications, 2014-06)
    An oxide film was prepared on AZ91D magnesium alloy by anodizing in solution containing sodium metavanadate (NaVO3). The corrosion resistance of the AZ91D magnesium alloy was investigated at fixed current density 10 mA/cm2 ...
  • Corrosion resistance by sodium metavanadate for AZ91D magnesium alloy 

    Nor Fadzilah, Toha; Siti Norbahiyah, Mohamad Badari; Mohamad Zamzuri, Mohd Zain (Trans Tech Publications, 2014-06)
    An oxide film was prepared on AZ91D magnesium alloy by anodizing in solution containing sodium metavanadate (NaVO3). The corrosion resistance of the substrate was investigated at a fixed current density 10 mA/cm2 for 5 ...
  • Effect of heat treatment on microstructure and corrosion behavior of Az91d magnesium alloy 

    Chye, Lih T.; Mohd. Zamzuri, Mohammad Zain; Siti Norbahiyah, Mohamad Badari; Khairul Azwan, Ismail, Dr.; Mohd Nazree, Derman, Dr.; Suhaimi, Illias (Trans Tech Publications, 2013)
    An AZ91D ingot in the as-cast condition was homogenized by heat treatment process. Then, the microstructures produced and corrosion behaviour after heat treatment was studied in detail. As-cast AZ91D was recrystallize by ...
  • Characteristic and corrosion studies of rare earth (REE) based anodizing on AZ91D magnesium alloy 

    Khalid Azadi, Mat Akhir; Mohd Zamzuri, Mohammad Zain; Mohd Nazree, Derman, Dr.; Siti Norbahiyah, Mohamad Badari (Trans Tech Publications, 2014-01)
    Oxide coatings on AZ91D magnesium alloy were prepared using anodizing technique with 10mA/cm2 current density for 5 minutes in electrolyte containing Mg (NO₃)₂ with NaVO₃ as an additive. The corrosion behaviors of different ...
