The influence of polymer composition on the wear of the metal surface during fretting of steel on polymer

摘要: Abstract The effects of the nature polymer on amount metal wear during fretting steel polymers in laboratory air have been studied under a range loads (130–330 g), amplitudes (3–10 μm) and frequencies (30–60 Hz). A number can cause damage to metal, which takes form adhesive transfer α-Fe 2 O 3 particles surface. depends counterface and, given set experimental conditions, increases order polytetrafluoroethylene (PTFE) polyethylene, polyvinylidene fluoride (PVDF), polychlorotrifluoroethylene (PCTFE), polysulphone, Polyvinylchloride (PVC), polymethylmethacrylate (PMMA), polycarbonate, nylon 66. No occurs when is PTFE only with polyethylene amplitude greater than 7 μm. These differences are explained terms properties polymers, as determined by their surface energetics.
