Influence of Titanium Oxide on Creep Behavior, Microstructure and Physical Properties of Tin-Antimony and Tin-Aluminum-Antimony Based Bearing Alloys

Abstract

Influence of adding titanium oxide (TiO2) nanoparticles on creep behavior, structure, mechanical and thermal properties of tinantimony-lead and tin-aluminum-antimony bearing alloys have been studied and analyzed. Stress exponent of tin-antimony-lead and tinaluminum-antimony-lead alloys decreased after adding titanium oxide. Elastic modulus of tin-antimony-lead increased after adding titanium oxide. Internal fiction of tin-antimony-lead and tin-aluminum-antimony-lead alloys varied after adding titanium oxide. Microstructure of tinantimony-lead and tin-aluminum-antimony-lead alloys changed after adding titanium oxide. Strengths of tin-antimony-lead and tin-aluminumantimony-lead alloys increased after adding titanium oxide. Thermal parameters of tin-antimony-lead and tin-aluminum-antimony-lead alloys varied after adding titanium oxide. The Sn97Sb51Pb1(TiO2)1 alloy has better bearing properties such as lowest internal friction, high elastic modulus and higher thermal diffusivity for industrial applications .

Titanium Oxide and their Effects on Structure, Physical Properties and Electrochemical Corrosion Parameters of Alloys

“…Dissimilar structure for Sn 60 Sb 15 Pb 5 Al 20 and Sn 58.5 Sb 15 Pb 5 Al 20 (TiO 2 ) 1.5 alloys are shown in scanning electron micrographs, Figure7, which agreed with x-ray analysis. That is meant adding TiO 2 caused a change in matrix microstructure[28].…”
