1. Statistical Analysis and Modelling of Engine Oil Degradation
University essay from Umeå universitet/Institutionen för fysikAbstract : An engine oil has several important properties it must fulfil in order to provide efficient engine operation. In addition to damping friction by lubrication, an engine oil must be able to cool, protect against corrosion, dampen vibrations and clean surfaces from contamination, wear and residual products.

2. Boric acid as a lubricating additive in fuels and in hydraulic oils
University essay from Uppsala universitet/Tillämpad materialvetenskapAbstract : Boric acid based fuel and oil additives were investigated in this study, with the aims to gain a deeper understanding of how the boric acid fuel additive behaves, to investigate the effect of low rates of fuel additive addition and tribofilm longevity, and to investigate how boric acid behaves as a hydraulic oil additive. Fuel additive experiments were performed in a reciprocating sliding rig with a cylinder on flat contact geometry with fuel additive sprayed on the contact repeatedly, whereas the hydraulic oil experiments were performed in a reciprocating sliding rig with a ball on flat contact with the oil and additive present from the start.

4. Bronze-Steel Friction Characteristics under the Lubrication of Modified Water/Glycerol Mixtures
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : Increasing environmental awareness has driven a lot of research to look into various environmentally friendly lubricants which can replace more conventional mineral oil based lubricants. This is true in particular for marine and hydropower applications where the risk of lubricant leakage can be damaging to the local environment. READ MORE

5. Who’s in charge? Electro-responsive QCM Studies of Ionic Liquid as an Additive in Lubricant Oils
University essay from KTH/Skolan för kemivetenskap (CHE)Abstract : Electrochemical quartz crystal microbalance has been employed to investigate electro-responsiveness of an ionic liquid as an additive in lubricant oils on a gold surface. Polarisation of the surface reveals changes in frequency where an increase in magnitude amplified the observed response, corresponding to a controllable alternation of the ionic liquid configuration on the surface as a function of applied potential.
