    • Dry sliding wear behaviour of A390 hypereutectic (Al–Si) alloy 

      Riyadh A., Al-Samarai; Haftirman, Idrus; Khairel Rafezi, Ahmad, Dr.; Yarub, Al-Douri (Universiti Malaysia Perlis (UniMAP)Pusat Pengajian Kejuruteraan Mekatronik, 2012-02-27)
      The behavior of wear for dry alloy A390 of (aluminum–silicon) casting which constitutes 16% Si is investigated. The lost of the wear rate is weighted and the volume decreases with increasing speed of sliding as well as ...

    • Evaluate the effects of various surface roughness on the tribological characteristics under dry and lubricated conditions for Al-Si alloy 

      Riyadh A., Al-Samarai; Haftirman, Dr.; Khairel Rafezi, Ahmad, Dr.; Yarub, Al-Douri, Assoc. Prof. Dr. (Scientific Research Publishing Inc. All rights reserved., 2012-07)
      The effect of surface roughness average of hypereutectic aluminum silicon alloys (with 16 wt% Si) on the friction and wear was investigated. Various surface roughness average (Ra) of different degrees was verified as well ...
