Originální abstrakt

Top–of–rail friction modifiers (FMs) represent an up–to–date approach to managing adhesion in the wheel–rail interface. The aim of this study was to investigate the role of typical water–based FM constituents in terms of adhesion and film formation. The ball–on–disc apparatus was employed to reach a rolling–sliding contact. The friction behaviour of various complex substances with different compositions was investigated in terms of adhesion and wear. The results showed that less complex substances, e.g. free of particles for friction modification, can provide required adhesion. Moreover, adhesion was not markedly decreased when the contact was overdosed. The performance of water–based substance/FM is greatly affected by evaporation of water. Surface analyses showed that substances are able to reduce wear and surface damage.
