In the present paper, sliding wear characteristics of seven weight% yttria stabilized zirconia (7YSZ) sol-gel deposited on to air plasma sprayed CoNiCrAlY bond-coated Inconel 800 superalloy has been studied. For this, sliding wear tests have performed on pin-on-disc friction and wear test rig by varying experimental parameters applied load, sliding velocity, disc speed and temperature as per L16 orthogonal arrays of Taguchi. Taguchi method has been used to perform experiments to know the effect of interaction of variables on dry sliding wear behavior. The optimal experimental parameters have been obtained by orthogonal arrays, signal-to-noise ratio (SNR) and analysis of variance (ANOVA) for uncoated and coated Inconel 800 superalloy substrate. Results have shown temperature as the most influencing parameter for uncoated samples and coated samples, both. However, compared with coated samples, applied load has been found significant factor for uncoated samples. It has been exhibited better wear resistance in the sol-gel derived YSZ coated surface of IN800 superallloy substrate.
