Friction and Wear Behavior of Moglice Polymer Composite through Dry Sliding Ball-on-Flat Reciprocating Test

摘要

This paper presents an experimental evaluation of friction and wear properties of a composite material - moglice - made by Diamant Metallplastic GmbH company, from Germany. This material is a polymeric matrix reinforced with particles of cristobalite (αSiO_2) and molybdenum disulphide (MoS_2). The material is recommended by the manufacturer for repairing metal parts. This material was tribologically tested in dry friction conditions, on a ball on flat configuration, using the reciprocating method on a CETR UMT-2 tribometer (Bruker Corporation). The counterpart was a steel ball. The tests were performed at room temperature in normal conditions of relative humidity of 40-60% using an average sliding speed of 3.5 mm/s. The tests were carried out at normal loads of 20, 30, 40 and 50N over a sliding distance of 100 m. The wear tracks obtained were optically examined with μSCAN laser profilometer (NANOFOCUS).
