In the presented research work the experiments have been performed by using design of experiments (DOE) L<sub>18 </sub>[OA] orthogonal array based on Taguchi S/N (signal-to-noise) ratio. The three control factors namely sliding speed, load and sliding distance varied to three levels (1, 2 and 3), respectively. One control factor has the sliding condition varied to two levels (l= Dry and 2= Cryogenic with LN<sub>2</sub>). The dry sliding condition has been made without any coolant. Cryogenic sliding condition has been made by using the direct supply of LN<sub>2</sub> at the interface of pin and disc. Wear volume loss has found to be 45-55% lower during cryogenic cooling with LN<sub>2</sub> as compared with dry sliding. (ANOVA) analysis of variance revealed that sliding condition is having the highest effect of contribution at 64.37%. Field emission scanning electron microscope (FSEM) images of the pins have shown (i) adhesion and edge fracture during dry sliding, (ii) clean and smooth surface found during cryogenic cooling. Field scanning electron microscope (FSEM) images of wear tracks showed (iii) delamination, cavities and plough during dry sliding and (iv) the surface generated during cryogenic sliding was clean with low debris. |
