真空充氩反复熔铸对烤瓷合金化学成分的影响
Effects of recasting in vacuum with argon on the chemical composition of ceramic alloys
摘要
Abstract
Objective This study aimed to determine the effect of recasting in vacuum with argon on the chemical compo-sition of cobalt-chromium (Co-Cr), commercially pure titanium (cpTi), palladium-based (Pd-based), and aurum-platinum (Au-Pt) ceramic alloys. Methods Without adding new alloys, Co-Cr, cpTi, Pd-based, and Au-Pt ceramic alloys were recast one to three times under the condition of vacuum compressive casting with argon. Before recasting, four previously cast ceramic alloys were treated with the corresponding method. After polishing, the chemical composition of the four ceramic alloys recasted one to three times were determined by energy-dispersive spectrometry. Results No significant difference was observed in the chemical composition of the four ceramic alloys recast 1-3 times (P>0.05). Conclusion Under the condition of vacuum with argon, the recasting had no obvious influence on the chemical composition of Co-Cr, cpTi, Pd-based, and Au-Pt ceramic alloys.关键词
