“…Vicent et al [20] investigated the effect of size particles on microstructure and mechanical properties of the Al 2 O 3 -TiO 2 coatings. Comparative investigation of Al 2 O 3 -TiO 2 coatings in terms of different depositing technique and their tribological properties at room temperature were studied [21,22]. Kusoglu et al [23] investigated the wear behaviour of flame sprayed Al 2 O 3 -TiO 2 coatings at room temperature.…”

In the present study, three coatings of Al2O3, Al2O3-13%(TiO2) and Al2O3-40%(TiO2) composite coatings were deposited by the thermally flame spray process. The comparative wear behaviour of the Al2O3-TiO2 coatings has been studied under high temperature levels up to 400°C with the help of a high temperature tribometer at a constant load of 40N. Prior to the tribo-test, the coating morphology and elemental analysis has been examined with the help of field emission scanning electron microscope (FESEM), elemental dispersion spectroscopy (EDS) and X-ray powder diffraction (XRD) techniques. The Mechanical properties have been also analyzed and reported. The results reveal that specific wear rate decreases with an increase in temperature for all the deposited coating except Al2O3 coating at 400°C. The overall friction coefficient of the coatings is decreasing with the increasing temperature. The Al2O3-40%TiO2 coating showed maximum sustainability against wear as well as a low coefficient of friction because of its low hardness and high adhesion properties. The examined worn surface validates the presence of brittle fracture and abrasive wear behaviour mechanism along with the oxidation wear, from room temperature to 400°C.

The present study focuses on the wear behaviour of a Al2O3-13 wt.% TiO2 composite coating deposited by a flame spray method for high temperature applications. The microstructural characterisation and mechanical properties, such as microhardness and surface roughness were studied. In addition, the porosity characterisation of the coating was studied through quantitative image analysis using the software Image_J. The tribological testing of the deposited coating was performed at four different temperatures, i.e., 25 °C, 100 °C, 200 °C and 400 °C, using a high temperature pin-on-disk tribometer. The specific wear rate decreases with an increase in temperature of upto 200 °C and then increases slightly at 400 °C, whereas the coefficient of friction declines with temperature rise. The dominant wear mechanism is three-body abrasion and brittle fracture followed by erosion and oxidation wear at high temperatures.
