    • Bending fatigue strength of case-carburized spur gears with boss 

      Imaduddin Helmi, Wan Nordin; Mohd Afendi, Rojan; Salmie Suhana, Che Abdullah; Mohd Hafis, Sulaiman (Universiti Malaysia Perlis (UniMAP)Pusat Pengajian Kejuruteraan Mekatronik, 2012-02-27)
      Studies on the spur gear, to increase the bending fatigue strength have been published by adopting gear with high pressure angle and positive addendum modification factor. However, studies on the spur gear with wide ...
    • Effect of deposition time on properties of ZrO2 coating prepared using electrolytic method 

      Siti Hawa, Mohamed Salleh; Terng, Lim Wuh; Mohd Nazree, Derman, Dr.; Mohd Zaidi, Omar; Salmie Suhana, Che Abdullah (Trans Tech Publications, 2013)
      AISI 440C martensitic stainless steel is one of the most widely studied engineering materials for its tribological properties. It is capable of attaining the best mechanical properties such as high strength and hardness ...
    • Effect of sintering time on the properties of LaYO3 doped with ZrO2 solid electrolyte 

      Salmie Suhana, Che Abdullah          ; Nur Hazwani, Samsudin; Najwa Shafiqa, Anwar; Imaduddin Helmi, Wan Nordin (Trans Tech Publications, 2013)
      LaYO3 doped-ZrO2ceramic with the composition La0.95Zr0.05YO3+δ was prepared via the solid state reaction. The samples were sintered at 1450 °C and sintering times in range of 6-15 hours have been varied for both doped and ...
    • Effects of rim and web thicknesses on root stresses of thin-rimmed helical gear 

      Imaduddin Helmi, Wan Nordin; Mohd Hafis, Sulaiman; Daing Idris, D. M N; Che Abdullah, S. S; Miyachika, Kouitsu; Ando, Kazuaki; Koide, Takao (Applied Mechanics and Materials, 2012)
      This paper presents a study on root stresses of thin-rimmed helical gears with web arrangement of various rim and web thickness. Thin-rimmed helical gears used in this study were meshed with solid helical gear. Root ...
    • Microstructural characterization of ZrO2 layer coating on martensitic stainless steel 

      Siti Hawa, Mohd Salleh; Mohd. Zaidi, Omar, Prof. Madya Dr.; Mohd Nazree, Derman, Dr.; Salmie Suhana, Che Abdullah (Trans Tech Publications, 2012)
      High carbon steel stainless steel such as 440C martensitic stainless steel, are commonly used for automotive components, such as ball bearings, races, gage blocks and valve. In this study, 440C steel was coated with ZrO2 ...
    • Preparation and characterization of silica aerogel immobilized with cyanex 301 for extraction of Zn(II) 

      Mst. Noorzahan, Begum, Dr.; Md Fazlul, Bari, Dr.; Salmie Suhana, Che Abdullah; Khairel Rafezi, Ahmad, Dr.; Nasim, Ahmed, Dr. (Trans Tech Publications, 2013)
      A new solid phase extractant silica aerogel immobilized with Cyanex 301 {bis(2,4,4- trimethylpentyl) dithiophosphinic acid} (SAWC) was prepared via a sol- gel method and investigated for the extraction of Zn(II) from aqueous ...
    • Two-step sintering of fine barium cerate-zirconate ceramics electrolyte 

      Salmie Suhana, Che Abdullah; Rohaya, Abdullah; Nafisah, Osman (Trans Tech Publications, 2014)
      Two-step sintering (TSS) was applied on the BaCe₀.₅₄Zr₀.₃₆Y₀.₁ O₂.₉₅ powder and the effect of the second step temperature (T2) during sintering process on the grain growth, density and hardness is reported. Normal sintering ...
