THE INFLUENCE OF THE MOTION PARAMETERS ON THE SURFACE LAYER OF METAL-POLYMER SLIDING PAIRS AT LOW TEMPERATURES
Journal Title: Tribologia - Year 2016, Vol 265, Issue 1
Abstract
The surface layer of the polymeric sliding materials co-operating with steel has an impact on the tribological properties at low temperatures. The goal of the present study was to determine the impact of the friction process parameters on the change in the surface layer of the polymeric materials. Three polymeric materials, namely PA6, PEEK, and PTFE, were tested. The materials were used for the sliding pairs with the typical construction steel C-45. At first, the tribological investigation at a low temperature T = (–50–0)°C was performed. Before and after that, the friction surface of the polymers, including the surface roughness and microhardness, were evaluated. During the experiment, variable parameters were the sliding velocity (v = 0.5 – 2 [m/s]) and the unit pressure (p = 0.5 – 3 [MPa]). The research has shown changes in the surface layer after the tribological tests at low temperatures. Strengthening and smoothing of the friction surface were observed, depending on the assumed process parameters.<br/><br/>
