Effect of adding titanium oxide nanoparticles (TiO2) on structure, elastic moduli, Vickers hardness, internal friction, electrical resistivity and thermal properties of tin-antimony-lead and tin-aluminum bearing alloys have been investigated. Elastic modulus, Vickers hardness and thermal diffusivity of Sn87Sb10Pb3 and Sn80Al20 alloys increased after adding TiO2 nanoparticles. Internal friction, thermal conductivity and specific heat of Sn87Sb10Pb3 and Sn80Al20 alloys varied after adding TiO2 nanoparticles. Adding titanium oxide nanoparticles improved bearing properties, such as strengthens and internal friction of Sn87Sb10Pb3 and Sn80Al20 alloys. The Sn85.5Sb10Pb3(TiO2)1.5 alloy has best properties for automotive industry. Also Sn78.5Al20(TiO2)1.5 alloy has best properties for marine applications.
