摘要/Abstract

摘要： 目的：探讨反复熔铸对纯钛烤瓷合金力学性能的影响。方法：纯钛经过1~3次单纯反复熔铸后,采用拉伸实验、弯曲实验、硬度实验对各代试件的力学性能进行测试。采用SPSS13.0软件包对数据进行统计学分析。结果：经不同次数熔铸的纯钛烤瓷合金试件,其弯曲强度无显著差异。经过2次、3次熔铸的纯钛烤瓷合金试件,其弯曲模量较1次熔铸的纯钛烤瓷合金显著升高(P<0.05)。拉伸强度、0.2%屈服强度随着熔铸次数的增加而升高(P<0.05)。经过3次熔铸的纯钛烤瓷合金试件,其延伸率较经过1次、2次熔铸的纯钛烤瓷合金显著降低(P<0.05)。经过3次熔铸的纯钛烤瓷合金试件,其显微硬度较经过1次、2次熔铸的纯钛烤瓷合金显著升高(P<0.05)。结论：纯钛烤瓷合金经1~3次单纯反复熔铸后,弯曲性能、显微硬度未下降,但拉伸性能下降。

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.
