Abstract :

The conducted experiments have enabled the establishment of a straight-line relationship between wear and testing time; wear intensity therewith changes in a self-organised manner with a decline early in the experiment and subsequent stabilisation. It has been found that the specimen rotation rate during accelerated tests should not exceed 850 min-1. Using epoxide compounds has led to creation of technologies that influenced profoundly the development of various industrial sectors [1,2,3]. Epoxy-resin-based materials are of vital importance when used as coatings of working surfaces. At the same time, there are few, fragmentary, and sometimes contradictory data about the behaviour of such compounds when the abrasive wear is highly intensive [4,5], what precludes the use of these polymer self-hardening materials and composites based thereon. Hence, laboratory studies of wearing are necessary since the use of composite coatings with various fillers and compositions offers extensive prospects in increasing service life of parts operated in abrasive media [6,7].
