Abstract

Abstract: PURPOSE: To investigate the influences of repeated casting on the mechanical properties of CP Ti ceramic alloy. METHODS: CP Ti ceramic alloy samples were prepared and recast 3 times without adding any new CP Ti ceramic alloy. The physical properties of each specimen were measured. SPPPSS13.0 software package was used for statistical analysis. RESULTS: No significant difference was found on the flexural strength of the CP Ti ceramic alloys that had been cast 2 or 3 times, compared with that of the alloys being cast only 1 time (P>0.05). However, the flexural modulus, tensile strength, 0.2% yield strength and surface microhardness of the CP Ti alloys being cast 2 or 3 times were significantly higher than those of the alloys being cast only 1 time (P<0.05). Elongation of the CP Ti alloys being cast 2 or 3 times was significantly lower than that of the alloys being cast only 1 time (P<0.05). CONCLUSIONS: Recasting may cause decreases in tensile properties of CP Ti ceramic alloy.
