Popis:	The anti-gallings and wear resistances of SiO2 particles coated with carbon were investigated by using a Falex (pin/vee block) friction machine, when they were added into lithium soap-lubricating grease as solid lubricants. The SiO2 coated with carbon showed higher seizure loads and better wear resistances than graphite. The lubricating actions of these carbon-coated SiO2 particles are due to their presences at the friction interface which decrease the direct contact between the friction surfaces,thus resulting in high seizure loads and wear resistances.
