【Abstract】 The effect of Rear Earth additive was studied on the mechanical properties and the electrochemical properties of the leadcalcium alloys with low calcium and high tin content.The tensile strength,toughness,hardness,constant current corrosion performances and gas evolution behavior were detected and analyzed.The results showed that the new kind of the lead-calcium alloys has good mechanical and corrosion-resistance properties.The strength of the alloys was improved with the adding the Rear Earth into the alloy,the ductility was also improved rapidly and the corrosion-resistance property was improved more.更多还原
