The effect of different polymer layers (polysulfone and polytetrafluoroethylene) on mechanical properties of stainless steel plates was studied. The "in vitro" behaviour of examined samples was determined on the basis of pH variations of the Ringer fluid during the incubation, also by conductivity measurements and by sample weight variations during 10 weeks immersion in solution. Scanning electron microscopy helped to co-relate the properties of stainless steel with different polymer layers applied on its surface. Layers adhesion to stainless steel surface was observed in more detail. Results showed that pH values of the Ringer fluid for polysulfone coated samples of stainless steel were lower than those for bare steel. Fluid conductivity presented continuous increase during incubation. The SEM micrographs showed that layers adhesion to stainless steel surface was better in the case of polytetrafluoroethylene.
