Reciprocating friction and wear properties of mesocarbon microbeads-based graphite and siliconized graphite

The friction and wear properties of mesocarbon microbeads-based graphite and siliconized graphite were investigated. At loads of 20-60 N, the graphite had low friction coefficient (0.15-0.26), while had high wear rate (0.039-0.50 × 10−3 mm3/m). Siliconized graphite had higher friction coefficient (0.375-0.40), while at higher loads of 40 N and 60 N, it had lower wear rates (0.15 and 0.18 × 10−3 mm3/m respectively). The main wear of ploughing resulted in low wear rate for siliconized graphite.
