    • 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 ...

    • Electrochemical corrosion behaviour of Mg-(Ca,Mn) sacrificial anodes 

      Shaiful Rizam, Shamsudin; Azmi, Rahmat, Assoc. Prof. Dr.; Mahdi, Che Isa; Mohd Nazree, Derman; Abdul Razak, Daud (Trans Tech Publications, 2013)
      The aim of the study is to identify the effect of Ca in Mg-Mn alloy on electrochemical corrosion behavior for the development of high performance sacrificial anode. Mg alloys were fabricated by casting technique under an ...

    • Failure investigation on rusty mesh strainer of petrochemical plant 

      Shaiful Rizam, Shamsudin; Harun, Mohd; Mohd Arif Anuar, Mohd Salleh; Hafizal, Yazid; Mazlee, Mohd Noor, Dr. (Trans Tech Publications, 2013)
      The wire material of filter mesh is made of 304 grade stainless steel. The failure to run properly was due to the impact of burst and torn. The client also expects that the failure was due to corrosion problems. A visual ...

    • High temperature creep and hydrogen embrittlement failure of a steam trap bypass tube 

      Mohd Arif Anuar, Mohd Salleh; Shaiful Rizam, Shamsudin; Darwin, Sebayang, Ir. Ing. Prof. Dr; Nik Noriman, Zulkepli; Sitompul, Anton; DIC, Syahril (Trans Tech Publications, 2013)
      A coal fired power plant with its normal operation temperature of 540°C in which its steam trap bypass tube in that power plant was totally fractured. The aim of this study is to explore the evidence related to the steam ...
