“…where α 1 and α 2 are the pressure-viscosity coeffi cients of pure oils at the specifi c temperature, and φ 1 is the segment fraction of component 1 (equation [4]) determined from the viscosities of the blends (equation [3]) by adjusting the parameter m. The model predicts a linear dependence of α mix on φ 1 (equation [9]). Application of equation (9) for two cases is illustrated in Figure 4.…”

“…Durak et al investigated the friction of journal bearings in mixed or boundary lubrication using blends of mineral oil with up to 50% of canola, 7 sunfl ower 8 or cottonseed oils. 9 The mineral oil that was used in the experiments had higher viscosity than the vegetable oils. Blending of mineral oil with canola oil led to decrease of the friction coeffi cient at all concentrations between 1 and 50% at 25 and 100°C.…”

Two polyalphaolefi ns, of higher and lower viscosity than vegetable oils, were used to make binary blends of varying compositions with soy bean and canola oils. The pure oils and the blends were used in viscosity and fi lm thickness investigations. The effects of composition and temperature on viscosity were found to agree well with the theoretical predictions of a simple mixing law. The fi lm thicknesses of the various blends under elastohydrodynamic conditions were measured at 20 N load, and varying entrainment speeds and temperatures. From the data, pressure-viscosity coeffi cients, α, as a function composition and temperature were obtained. The resulting α values were compared with theoretical predictions. Experimental values of α as a function of composition showed a slight negative or no deviation from the values predicted by an ideal mixing model. On the other hand, experimental values of α displayed a mild decrease with increasing temperature, while the model predicted a sharp decrease with increasing temperature. Published in

In the present work, an attempt has been made to develop the indigenous formulation for metalworking lubricants by replacing mineral oils partially with non-edible industrial oils like rapeseed and karanja oil. Metalworking formulations consist of vegetable oil, mineral oil, an emulsifi er and commercial additives for better performance. Non-edible vegetable oils such as karanja and rapeseeds are renewable, biodegradable and cheaper than synthetic fl uids. The constituent vegetable oils and mineral oils were evaluated for physico-chemical characteristics and blended as per the saponifi cation value and viscosity requirements of the reference oils. The so formulated oils are taken as 5% oil-in-water emulsion and tested for lubricity, load bearing capacity, particle size distribution, wear test, weld load test and plate-out test. Performance of all formulated oils was compared with that of the reference oils, and optimized to meet the market requirements.
