Effect of C_2Cl_6 and Ca Addition for Preventing to the Surface Oxidation of Molten Magnesium

摘要

In this study, the effect of C_2Cl_6 and Ca addition for preventing to the surface oxidation of moltenrnmagnesium was investigated. In order to confirm the protective surface characteristic of molten magnesium by them, wernadded into molten AM100A alloy at 700℃ and then the melts were slowly cooled in air. Effect of the protective molten surfacernby adding them was more increase than only using Ar gas. These results are due to the formation of the compact oxide filmsrnover molten surface by adding them.
