反复熔铸对钴铬烤瓷合金力学性能影响的研究
Study of the mechanical properties of Co-Cr ceramic alloy after recasts
摘要
Abstract
Objective To study the mechanical properties of Co-Cr ceramic alloy after recasts. Methods Co-Cr ceramic alloy cast samples were prepared and recast for 3 times without adding any new Co-Cr 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 east for different times, the Co-Cr ceramic alloy showed no significant differences on their tensile strength, 0.2％ yield strength, percentage of elongation, flexural strength, flexural modulus and Vickers hardness. Conclusion Co-Cr ceramic alloy can be recast for 3 times at least, without decrease of the mechanical properties.关键词
