Abstract
In this study the results of the dry wear tests of composite material used to repair brass made parts are presented. The material belongs to Multimetall Messing category. It has a polymer matrix reinforced with Cu, Zn, Sn particles, and various allotropic forms of silicon dioxide (SiO2). This composite material was tribologically tested in dry friction reciprocating conditions, in ball-on-flat configuration, using the tribometer CETR-UMT-2. The counterpiece was a steel ball. The tests were performed at normal loads of 20, 30, 40 and 50N, over a distance of 100 m, at an average sliding speed of 3.5 mm/s, at room temperature and relative humidity of 50-60% . The results of the analysis were compared with the similar ones obtained under the same conditions for brass.
