【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(P0.05)。拉伸强度、0.2%屈服强度随着熔铸次数的增加而升高(P0.05)。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(P0.05)。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(P0.05)。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]:Objective: to investigate the effect of repeated melting casting on mechanical properties of pure titanium porcelain alloy. The mechanical properties of the specimens were tested by hardness test. The data were analyzed statistically by SPSS13.0 software package. Results: the pure titanium porcelain alloy specimens were fused and cast for different times. There is no significant difference in bending strength. The pure titanium porcelain alloy specimens, which have been melted and cast twice and 3 times, The flexural modulus of the alloy is significantly higher than that of the pure titanium porcelain alloy cast in one time. The tensile strength of 0.2% yield strength increases with the increase of casting times. The elongation of pure titanium porcelain alloy was significantly lower than that of pure titanium porcelain alloy cast once and twice. The microhardness of the alloy was significantly higher than that of the pure titanium alloy cast once or twice. Conclusion: the bending property, microhardness and tensile property of the pure titanium porcelain alloy after 1 or 3 times of simple repeated melting and casting are not decreased, but the tensile properties are decreased.
