Wear study on few engineering polymers rubbing against 316L stainless steel disc: Experimental tests will be carried out with typical pin-on-disc (inclined pin) over various speed and load combinations; primarily PEEK and PEI will be tested. More focus will be given on the role of counter face surface roughness on wear of polymers: Worn surface characterization will be tried. Characterization of the counter surface roughness with various techniques and their inclusion in the theoretical polymer wear model: Extensive measurements will be done with the contact surface profilometer and analysis will be carried out to obtain a suitable surface roughness data for theoretical model. An account of asperity slope on wear of engineering polymers: Both experimental and theoretical investigations will be carried out. Characterization of the proposed wear severity chart: Comparative study on theoretical and experimental results will be carried out. Study on the roll of visco-elastic deformation on friction and wear of polymers. Work on experimental verification of Ratner’s equation for polymers and polymer composites. Study on the issues with microstructural instabilities in polymer and its influence on wear: Strain rate response will be introduced. Characterizing self-lubricating behaviour of few polymers while rubbing against hard metal counterface: Wear debris analysis will be tried. Work on connecting the wear model based on asperity deformation with the bulk system. Investigation on the role of interaction (synergistic) between individual contact spots on wear. Work on developing polymer wear model by Whitehouse-Archard asperity model.
