ABSTRACT
The present work discusses the effect of the magnetic field on the friction and wear of brass sheets scratched by a steel insert at dry and lubricated by vegetable oils and dispersed by polymeric particles such as polyethylene (PE), polyamide (PA6) and polymethylmethacrylate  (PMMA).
 
Experimental results showed that, friction coefficient at dry and oil lubricated brass surface displayed higher values than that observed for steel. As the magnetic field is applied, friction coefficient drastically decreased. Polymeric particles caused significant reduction in friction coefficient. Application of the magnetic field showed further friction decrease. Under the action of the magnetic field, friction coefficient slightly decreased for dry and oil lubricated sliding. Castor, almonds, camomile, jasmine, maize, and olive oils displayed lower friction.
Wear displayed relatively higher values than that observed for steel. Camomile and almonds oils showed the lowest wear values. Application of the magnetic field slightly decreased wear. Olive, jasmine and maize oils displayed the lowest wear values. Presence of polymeric particles on the sliding surfaces slightly decreased wear. Magnetic field showed wear decrease. Dry sliding displayed relatively lower values of wear. Castor and maize oils showed good wear resistance.
