Effect of small addition of aluminium on electrochemical corrosion behaviour of magnesium-calcium sacrificial anode in underground environment
(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 ...
The effect of heat treatment on the anode efficiency of Magnesium sacrificial anode
(Universiti Malaysia Perlis, 2009-12-01)
High efficiency sacrificial anode from Mg alloy is needed as it has higher capability of protecting underground metal structure against corrosion in cathodic protection. Solution treatment was applied to Mg sacrificial ...
Potentiodynamic polarization of Mg-0.22ca alloys containing minor element of Aluminium
(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 ...
Effect of solution treatment on Mg galvanic anodes in CaSO4 – MG(OH)2 aqueous solution
(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 ...
Effect of Ca on the performance of Mg-Mn sacrificial anodes by electrochemical corrosion techniques
(Universiti Malaysia Perlis, 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 ...
