Study of the mechanical properties of Co-Cr ceramic alloy after recasts / 华西口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the mechanical properties of Co-Cr ceramic alloy after recasts.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>Co-Cr ceramic alloy can be recast for 3 times at least, without decrease of the mechanical properties.</p>
