金属元素铍对烤瓷合金铸流率影响的实验研究

The experimental study of the effect of Be on the castability of alloy for porcelain-fused-to-metals

目的:比较两种烤瓷合金的铸流率,了解金属元素铍对合金铸流率的影响。方法:采用网状试件,通过直接法计算两种烤瓷合金的铸流率(Cv)值,比较两种包埋料(F-1和F-2包埋料)对两种合金铸流率的影响。结果:含铍烤瓷合金和不含铍烤瓷合金的铸流率均在95%以上,两种烤瓷合金的铸流率无显著性差异(P>0.05);两种包埋料对两种烤瓷合金的铸流率的影响在统计学上均无显著性差异(P>0.05)。 结论:金属元素铍对烤瓷合金的铸流率无重要影响;两种包埋料对两种烤瓷合金的铸流率无显著影响。

Objective: To investigate the effect of beryllium on the metal castability by comparing the castability of twokinds of alloy for porcelain-fused-to-metals. Methods: The effects of two investments on the castability were compared,through directly calculating the castability values of the two kinds of porcelain-fused-to-metals using net patterns. Results:There had no significant difference between Ni-Cr -Be alloys and Be-free alloys (P>0.05) in their castability, both wereover 95%.Conclusion: The presence of Be in Ni-Cr alloys can not increase the castability of alloys. The two investmentshave no significant effect on the castability of the two kinds of porcelain-fused-to-metals.
