    In this study, an investigation of the effects of ceramic coatings on diesel engine performance and exhaust emissions was presented. Tests were carried out a range of engine speeds at low, middle and high load conditions ...
  • Şen, Uğur; Şen, Şaduman; Yılmaz, Fevzi (TRANS TECH PUBLICATIONS LTD, 2004)
    In this work, some surface properties of ductile cast irons were improved by boronizing thermo-chemical process. Boronizing was performed in a slurry salt bath consisting of borax, boric acid and ferro-silicon at 850degreesC ...
  • Okumuş, Sefer Cem (TRANS TECH PUBLICATIONS LTD, 2004)
    In this study, low pressure plasma spraying (LPPS) demonstrated as a viable technique to producing fine-grained samples from complex Mo-Si-B intermetallics. Microstructure and oxidation behavior of the coatings were studied.
  • Özbek, İbrahim; Şen, Şaduman; İpek, Mediha; Bindal, Cuma; Zeytin, Sakin (PERGAMON-ELSEVIER SCIENCE LTD, 2004)
    In the present study, some properties of borides formed on AISI 440C stainless-steel have been investigated. Boronizing was carried out in a solid medium consisting of EKabor(R) powder at a temperature of 950degreesC for ...
  • Akbulut, Hatem (PERGAMON-ELSEVIER SCIENCE LTD, 2004)
    Ti-6Al-4V alloys, which were exposed to an explosive shock process, were nitrided in nitrogen plasma in the temperature range of 700-900degreesC for 3-12 h. During the plasma nitriding, the surface layer consisted of TiN ...
  • Şen, Şaduman; Şen, Uğur; Bindal, Cuma (TRANS TECH PUBLICATIONS LTD, 2004)
    The present study reports on boride layer growth kinetics of borided AISI 4140 steel. Steels were boronized in molten borax, boric acid and ferro-silicon bath at 1123degreesK 1173degreesK and 1223degreesK for 2, 4, 6 and ...
  • Akbulut, Hatem (PO BOX 17, 3300 AA DORDRECHT, NETHERLANDS, 2004)
    In the present study, Ni coatings have been deposited on glass microscope slides at substrate temperatures of 300, 350, 400 and 450 degreesC. The depositions were performed by evaporating the metallic Ni source in a ...
  • Türk, Ahmet (TRANS TECH PUBLICATIONS LTD, 2004)
    In this study, low carbon steel substrate was coated with WC-Ni powder by using plasma spray process in order to increase the wear and corrosion resistance of the material. Wear tests were applied to the produced samples ...
