In this issue, we cover our usual diverse range of research taking place in the tribological world.
Five workers from different universities in Taiwan have combined their expertise to formulate neural networking approach to the stiffness of balls used in rolling bearings. It is not obvious if this work will allow advances to be made in the design of bearings, but it may help to cement in place knowledge gained from the practical world.
Professor Kaleli, working in Turkey, has been looking at additive layer formed by engine oils on different types of materials and mechanical interfaces. Some interesting points are raised that will clearly be applicable to other oil types when hydrodynamic lubrication is not being achieved.
Doctor Omar from Egypt has been investigating polymeric surfactants used in metal working fluids. These components are looked at from their ability to both emulsify and provide intermachining stage corrosion protection.
Researchers in India have been mathematically modelling the benefits obtained when magnetic fluid is used to lubricate a slider bearing.
Workers in Turkey have been looking at the manufacturing methods used to produce calcium sulphonate. This component is widely used in engine oils and this work, which is continuing, is aimed at producing a component more accurately matched to the engines technical requirements.
We hope these papers will be of general interest and of course we do welcome any comments you may wish to make.
