STUDY OF RESISTANCE TO ABRASIVE WEAR OF MULTICOMPONENT POLYOXYMETHYLENE COMPOSITES

Journal Title: Tribologia - Year 2016, Vol 265, Issue 1

Abstract

The article presents the results of the comparative tribological study of the resistance of multicomponent polyoxymethylene (POM) composites to abrasive wear. The fillers for the studied POM matrix composites were a PTFE powder, the bronze powder, chopped glass fibre, and glass microballs, which were used both individually and in various combinations. Quantities of the composites were developed based on the simplex plan of the experiment. For the research, a Tester T-07 was used as a test stand. The study was conducted in the presence of loose abrasive, electrocorundum F90, subjected to the same conditions of friction for all the tested composites. The study has shown that the most effective compound in increasing resistance to the abrasive wear of the POM composites is the powder of bronze and the hybrid glass filler; whereas, the PTFE powder caused a slight reduction in the resistance to abrasive wear. In order to explain the mechanism of the abrasive wear of the studied composites, a microscopic examination of their friction surface before and after friction was conducted. Based on that study, the effect of particular fillers on the abrasive wear resistance of the tested POM composites was determined.<br/><br/>
