Effect of Ca on the performance of Mg-Mn sacrificial anodes by electrochemical corrosion techniques
Shaiful Rizam, Shamsudin; C. I., Mahdi; Mohd Nazree, Derman; A. M. H., Firdaus; A. R., Daud; T., Loshniban (Universiti Malaysia PerlisSchool of Microelectronic Engineering and Institute of Nano Electronic Engineering (INEE), 2009-12-21)The aim of the study is to identify the effect of Ca in Mg-Mn alloy on electrochemical corrosion behaviour for development of high performance sacrificial anode. Mg alloys were fabricated by casting technique under an ... -
The effect of F-75 alloy mixed with HAP on microstructure in corrosion test for biomaterial applications
Rohaya, A. M.; Shamsul Baharin, Jamaludin, Prof. Madya Dr.; Shaiful Rizam, Shamsudin (Universiti Malaysia PerlisSchool of Materials Engineering & School of Environmental Engineering, 2010-06-09)Co-Cr-Mo (ASTM: F-75) alloy is generally used because of their mechanical properties, good wear and corrosion resistance as well as biocompatibility. In order to obtain chemical similarity and interfacial bond form between ... -
Effect of small addition of aluminium on electrochemical corrosion behaviour of magnesium-calcium sacrificial anode in underground environment
Shaiful Rizam, Shamsudin; G., Sasirehka; A. M. H., Firdaus; C. I., Mahdi; D. M., Nazree; A. R., Daud; A. A., Azrem (PETRONAS, 2009-07-20)The effect of small addition of Al on the electrochemical performances was investigated by open circuit potential and Tafel Extrapolation method. The results show that open circuit potential reveals as-cast Mg containing ... -
Effect of solution treatment on Mg galvanic anodes in CaSO4 – MG(OH)2 aqueous solution
A. M. H., Firdaus; Shaiful Rizam, Shamsudin; Shamsul Baharin, Jamaludin, Prof. Dr.; M. N., Derman; Mohd Fitri, Mohamad Wahid; C. I., Mahdi (PETRONAS, 2009-07-20)The effect of heat treatment on the Mg anode was investigated in CaSO4-Mg(OH)2 aqueous solution. The Mg sample was solutionised at 150oC, Pure and untreated Mg anode were also studied as a reference. Eoc and Tafel corrosion ... -
Potentiodynamic polarization of Mg-0.22ca alloys containing minor element of Aluminium
Shaiful Rizam, Shamsudin; Mohd Nazree, Derman; C.I., Mahdi; Azmi, Kamardin; Abd. Razak, Daud; Mazlee, Mohd Noor; A.M.H., Firdaus; G., Sasirehka (Universiti Malaysia Perlis, 2009-12-01)Mg alloys played a significant role in replacing the existing sacrificial anodes. To maintain the negative potential and its capability in preventing corrosion, Ca and Al was added as alloying elements. Polarization curves ...
