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 cast 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.
