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 heat treatment on the open circuit potential of magnesium sacrificial anode
A. M. H., Firdaus; Shaiful Rizam, Shamsudin; Shamsul Baharin, Jamaludin; M. N., Derman; Mohd Fitri, Mohd Wahid; M. Z., Ruhiyudin (University of Malaya, 2009)Magnesium sacrificial anode that possess high value of open circuit potential, Eoc is needed as it can protect larger area of underground metal structure in cathodic protection. Solution treatment was applied on magnesium ... -
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 ...
