烧结温度对煤沥青中间相基炭材料的微观结构和摩擦性能的影响
Effect of sintering temperature on friction and microstructure of carbon material deriving from coal tar pitch
摘要
Abstract
Isotropic bulk carbon was prepared through cold-press sintering process with mesocarbon microbeads(MCMB) as raw materials and phenol aldehyde resin as the binder. The effects of sintering temperature on the shrinkage and the wearability were investigated. The crosssection microstructure and the scratch were observed by SEM. It is indicated that the weight loss and the volume shrinkage of bulk MCMB occur in the low temperature region. The dense microstructure was obtained after heat treatment at 900-1 300 ℃. The density and the friction coefficient of samples as prepared reach 1.62 g/cm^3 and 0. 202 respectively. The wearability of carbon materials was improved due to the compact microstructure.关键词
