Effects of lubrication oil and solid lubricants on friction and wear properties of si-particle dispersed al sintering bearing materials

The tribological properties of the new developed Si-particle dispersed Al sintering materials were investigated. The materials impregnated lubricant oil, semi-solid state Vaseline with solid lubricant and solid state Vaseline were experimented by using two disc end sliding contact testing machine. (1) The impregnated semi-solid state Vaseline with MoS₂ type solid lubricant has the effects on improvement of friction, wear and scuffing limit compared with the impregnated lubricant oil. The scuffing limit (PV value, P : contact pressure, V: sliding velocity) was improved about 45%. (2) The impregnated solid state Vaseline with MoS₂ is effective in improvement of the tribological properties for sliding bearing materials. The scuffing limit was improved about 52% compared with the impregnated material of lubricant oil.
