Effect of base oil polarity on micro and nanofriction behaviour of base oil + ZDDP solutions

Effect of base oil polarity on micro and nanofriction behaviour of base oilzZDDP solutions

Ball on disc tribometer and atomic force microscopy (AFM) were used to analyse the effect of base oil polarity on the friction behaviour of steel–steel contacts lubricated with base oilzzinc dialkyldithiophosphate (ZDDP) solutions. Understanding the lubrication properties of the first chemisorbed layer of additives on work pieces yields important information for the optimisation of lubricant fo...

Effect of Wax Content in Hydrocracker Unconverted Oil on Viscosity Index and Yield of Lubricant Base Oil 150N

Hydroprocessing has become the main technology for the production of API Group II and III base oils. One of the key properties is viscosity index for Group II and III base oils. The effect of wax content in hydrocracker unconverted oil on viscosity index and yield was studied in a 400 kton/year hydroisomerization dewaxing plant at a total pressure of 15 MPa, a feed rate of 38 ton/hour, and a ga...

Electrical and Thermal investigation of Transformer Oil base Nanofluids

Transformer oil is one of the most important materials which are used in electrical and transformer industrial. The main function is protection and insulation of transformer core components, as well as heat transfer from its core to environment. Improving the performance of this material has been one of the researchers' concerns. The effect of different nanoparticle on the electrical breakdown ...
