Abstract

Electrochemical corrosion behavior, elastic modului, internal friction, Vickers hardness, thermal performance and microstructure of Sn80Al20, Sn70Al20Bi5Zn3Cu2, Sn65Al20Sb5Pb5Cd5, Sn70Al20Sb5Ag3Zn2 and Sn63Al20Sb10Pb5Zn2 alloys have been investigated. Internal friction of Sn80Al20 alloy decreased after adding Bi- Zn- Cu or Sb- Pb- Cd or Sb- Ag- Zn or Sb- Pb- Zn elements. Elastic modulus and lattice microstrain of Sn80Al20 alloy decreased after adding Bi- Zn- Cu or Sb- Pb- Cd or Sb- Ag- Zn but it’s increased after adding 10%Sb- 5%Pb- 2%Zn. Vickers hardness of Sn80Al20 alloy varied after adding Bi- Zn- Cu or Sb- Pb- Cd or Sb- Ag- Zn or Sb- Pb- Zn elements. The corrosion rate of Sn80Al20 alloy in 0.5 M HCl increased after adding Bi- Zn-Cu or Sb- Ag- Zn or Sb- Pb- Zn elements but it’s decreased after Sb-Pb-Cd elements. The corrosion current density (icorr) of Sn80Al20 alloy in 0.5 M HCl increased after adding Bi- Zn-Cu or Sb- Pb- Cd or Sb- Pb- Zn elements but it’s decreased after Sb-Ag-Zn elements. The Sn70Al20Sb5Ag3Zn2 alloy has the beast properties for bearing applications.
