Abstract

The aim of the study is to investigate the influence of induction magnetic field on friction coefficient displayed by steel sliding against oil lubricated polymers.Induction magnetic field was applied with different fluxes of 0.1, 0.2, 0.3 and 0.4 mG intensity.Experiments were carried out using steel pin sliding on PMMA and PTFE sheets at dry sliding. Then paraffin and glycerin oils were dispersed by aluminium, copper, iron and graphite particles of 10 wt. % content.
 
The experiments showed that, sliding of steel against PMMA displayed the highest value of friction coefficient at dry sliding, while oil lubricated sliding showed relatively lower values. Slight friction decrease was observed as the intensity of the magnetic field increased. Paraffin oil showed the lowest friction values. The friction decrease might be attributed to the effect of the magnetic field which increased the viscous effect of the oil. Besides, polar molecules of the oil could significantly improve friction due to their adsorption on the sliding surfaces, where they orient themselves with the polar end directed towards the metal surface making a close packed monomolecular or multimolecular layered structure resulting in a surface film believed to inhibit metal-to-metal contact and progression of pits and asperities on the sliding surfaces.
 
Sliding against PTFE showed relatively low values at dry sliding. Application of magnetic field caused further friction decrease with increasing flux intensity. Magnetic field caused slight friction decrease in the presence of aluminium particles. Friction coefficient displayed by copper and iron particles showed slight increase with increasing flux intensity. When oil was dispersed by iron particles, magnetic field caused slight friction increase.
