LF4合金在磷酸盐-氢氧化钠溶液中的微弧氧化

Microarc Oxidation of LF4 Alloy in Mixed Phosphate Electrolytes

在磷酸盐混合体系中对 L F4合金进行微弧氧化 ,制得了厚达90 μm、显微硬度超过 12 0 0 HV的陶瓷氧化膜 .采用电子能谱 (EDS)、X射线衍射 (XRD)和扫描电镜 (SEM)等表面分析方法综合分析了膜层的成分、形貌及结构 ,并初步讨论了 L F4合金微弧氧化膜的形成过程 .

Ceramic oxide film,which shows a thickness of 90μm and a hardness of surpassing 1200HV,is obtained on LF4 alloy by microarc oxidation in mixed phosphate solution.The content,appearance and structure of the film is checked with EDS,XRD and SEM.Formation process of this film is also proposed preliminarily.
