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 ... -
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 ... -
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 ...
