500 ## - GENERAL NOTE
General note All mechanical systems require lubrication between interacting surfaces to avoid failure of<br/>mechanical components and to decrease the losses due to friction, especially for the interacting<br/>bodies that operate in boundary lubrication regimes. Due to the decrease in the reserve of mineral<br/>oils, increasing environmental concerns, and difficulties in the disposal of non-biodegradable<br/>conventional lubricants, a trend is increasing amongst researchers to produce more environmental<br/>friendly lubricants. The use of bio-lubricants as an alternative to mineral based oil is limited due<br/>to its low thermal stability. Ionic liquid are molten salts which are environment friendly and can<br/>be used as additive to bio-lubricants to enhance its physiochemical properties. The effectiveness<br/>of ionic liquid in bio-lubricants depends upon a lot of factor amongst which its miscibility with<br/>that particular lubricant plays an important role. Ionic liquids make strong interaction with polar<br/>lubricants and hence can be effectively used as additives to bio-lubricants. Among ionic liquids<br/>phosphonium based ionic liquids are found to show best results with lubricants and hence is used<br/>in this study.<br/>In this thesis tribological performance of phosphonium-based ionic liquid Tri hexyl tetra decylphosphonium bis (2, 4, 4-trimethylpentyl) phosphonate when used as an additive to Cottonseed<br/>oil, Rattan Jot oil, Waste Cooking oil and Polyalphaolefin (PAO) will be studied at different<br/>operating conditions and results will be compared with conventional PAO base oil. The physical<br/>properties of these oils were already investigated by a previous student Tehreem Naveed[1] and<br/>their tribological analysis is done in this study. Tribological performance of all lubricants were<br/>studied using a four ball tribometer and its wear scars were determined using an electronic<br/>microscope OLYMPUS. From this study it was found that with the addition of ionic liquid,<br/>tribological performance of all bio-lubricants enhanced. Ionic liquid does not have much effect on<br/>the tribological performance of PAO. Rattan Jot oil was found to have the best tribological<br/>properties with and without addition of ionic liquid into it.
