Effects of Lubrication Oil and Solid Lubricants on Friction and Wear Properties of Si-Particle Dispersed Al Sintering Bearing Materials

Kenichi TSURU and Susumu MATSUMOTO

Abstract: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, ‡X: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.
