Abstract

The aim of the present study is to investigate the friction coefficient displayed by sliding of bearing steel on polytetrafluoroethylene (PTFE) and polymethyl methacrylate (PMMA) at dry and in the presence of paraffin and glycerin oils​​. Besides, particles of iron (Fe), copper (Cu), aluminum (Al) and graphite (C) powders are added to the oils in 10 wt. % concentration. The grain size of the particles was ranging between 50 - 80 µm. The normal loads used are 2, 4, 6, 8, 10, 12, 14 and 16 N. While sliding velocity was 2 mm/s.   It was found that dispersing the surfaces of PMMA and PTFE by Fe, Cu, Al and C particles decreased friction coefficient at dry sliding, where the effective decrease was presented by C. Sliding on PTFE showed lower friction than that observed for sliding on PMMA. At oil lubricated sliding, steel/PMMA displayed higher friction than that detected for oil dispersed with the tested particles. Sliding of steel on PMMA lubricated by paraffin and glycerin oils and dispersed by Al displayed lower friction values than that shown by sliding on PTFE. For lubricated sliding by paraffin and glycerin oils, the use of PMMA as bearing material can be recommended.
