Abstract 1- Improve the corrosion resistance and Wettability by adding Al content to Sn-9Zn alloy. ( Sn87-Zn9-Al4 ). 2-Improve the melting point by adding (5%In)= 187°C and (In5Bi3 )=184°C to Sn-9Zn alloy ( Sn83Zn9In5Bi3 ). 3-Improve the mechanical properties by adding (In5Bi3) to Sn-9Zn alloy ( Sn82Zn9In5Bi3 ). 4 - Adding In to Sn-9Zn alloy cause Affects negatively in corrosion resistance.5- Adding Al or In or Al-In or In-Bi to Sn-9Zn alloy Improve the Vickers microhardness and Internal friction. 6- The alloy (Sn91-Zn9) have best Electrical conductivity . |
