옻칠 기법을 활용한 마그네슘 장신구 제작

Abstract

This research is about a jewelry production with magnesium, non-precious metal. Since magnesium is the lightest metallic material commercialized, it is appropriate for making voluminous but light and comfortable fitting jewelry. However, it has been used mainly in the field of large scale manufacturing industry such as automobile or electronic device so far, and cases used as material of jewelry can hardly be found. In this research, two problems in using magnesium as jewelry material were dealt; first was a matter of the forming process. Warm press forming process and dia-casting process used to work magnesium alloy presently are not proper to make jewelry which is sensitive to trends and value on diversity. So, the process to cut masses of magnesium alloy to various formed jewelry was researched. Second is the issue of surface treatment and coating suitable for jewelry. Since magnesium alloy has vary fast corrosion properties, it requires surface treatment and coating to improve the corrosion resistance. While film forming through chemical and electrical method or a chemical coating application is common, for jewelry contacted with human body, more eco-friendly and high value surface treatment and coating processes are needed. Therefore, Traditional Lacquer Techniques which can improve functionality and artistic value of jewelry are used. In this paper, pre-treatment processes to improve adhesive strength and durability of traditional lacquer on the magnesium surface are researched, and it is possible to get durable traditional lacquer films through proper chemical treatments to magnesium. But more research is needed about traditional lacquer techniques of new color and texture that can reflect unique aesthetic properties, since it is impossible to expose the magnesium surface.
