    Wear behavior of flame-sprayed Al2O3 -TiO2 coatings on plain carbon steel substrates
    (2005) Kusoglu I.M.; Celik E.; Cetinel H.; Ozdemir I.; Demirkurt O.; Onel K.
    In this study, Al2O3-TiO2 powders were sprayed using a flame-spray technique after a NiCrMo bond layer was deposited on plain carbon steel substrate. The produced layers were characterized by X-ray diffraction (XRD), optical microscope, scanning electron microscope (SEM) including energy-dispersive spectroscopy (EDS), surface roughness and microhardness tester. Friction and wear behaviour of the coatings were also evaluated in the present study. The Al2O3-TiO2 coatings were subjected to sliding wear against AISI 303 stainless steel counter body under dry and acidic environments. A pin-on-plate type apparatus was used with normal loads in the range of 49-129 N. Wear resistance of the coatings in acid environment is better than that in dry conditions. © 2005 Elsevier B.V.

    Effects of coil design on induction welding of sintered iron based compacts
    (Carl Hanser Verlag, 2014) Çavdar U.; Kusoglu I.M.
    Sintered iron based compacts were welded by applying a high frequency induction process. The cross-sections of the compacts were square in shape so two different coil shapes, cylindrical and square, were studied with respect to the effect of magnetic flux. The effect of welding duration on the macrostructural changes and mechanical properties of the induction welded compacts were investigated for welding durations of 3, 5 and 10 minutes. © Carl Hanser Verlag GmbH & Co.
