Tribological Properties of Polymer Composites Reinforced with Silver Particles

Abstract:

The paper presents results of investigations on a potential for utilisation of waste materials, containing silver powders, ceramics and polymer, for production of PTFE-matrix composites. The waste is a mix of Ag powders (10 – 15%), SiC and Al₂O₃ powders (20 – 50%) and polymeric powders (20 –50%). For composite production, high-temperature press moulding method was applied. Reinforcing materials and the matrix powder were mixed and subjected to the pressing process in a graphite mould at 350oC. Composite specimens containing 25% Ag, 50% Ag and 75% Ag were obtained. For the obtained composites, density, HB hardness and a friction coefficient were determined. The friction coefficient was evaluated in the “pin-on-block” test with the sliding distance of 2500 m and a load of 25 N with no lubrication. Wear of the composites was assessed based on a profilometry analysis. The obtained results suggest that the composites may be applied for manufacturing of components resistant to abrasive wear with a required, low friction coefficient.
