反复熔铸对金铂烤瓷合金力学性能影响的研究
Physical properties of Au-Pt ceramic alloy after recasting
摘要
Abstract
Objective To investigate the influences of recasting on the mechanical properties of Au-Pt ceramic alloy.Methods Au-Pt ceramic alloy samples were prepared and recast for 3 times without adding any new Au-Pt ceramic alloy.The tensile strength,0.2％ yield strength,percentage of elongation,flexural strength,flexural modulus and Vickers hardness of each specimen were measured.Results Being cast for different times,the Au-Pt ceramic alloy showed no significant differences on their tensile strength,0.2％ yield strength,percentage of elongation,flexural strength or Vickers hardness.The flexural modulus of the Au-Pt alloys being cast for 2 or 3 times was significantly higher than that of the alloys being cast for 1 time (P＜0.05).Conclusion Au-Pt ceramic alloy can be recast for 3 times at least,without any decrease in the mechanical properties.关键词
