Abstract
Ti2SnC conductive ceramics were prepared by mechanical alloying and spark plasma sintering using Ti,Sn and C asstarting powders. The effect of sintering temperature on the phases,microstructure,hardness,friction and wear properties ofsintered block was investigated. The results demonstrate that when the temperature is from 600 ℃ to 1 000 ℃,with the increaseof sintering temperature,hardness and friction coefficient are decreasing;The sintered block sintered at 1 000 ℃ has lowesthardness and smallest friction coefficient;Ti2SnC begins to decompose when the temperature is higher than 1 000 ℃,hardness begins to increase and friction coefficient decreases.
