옻칠을 활용한 마그네슘합금 판재의 표면장식

Abstract

The Purpose of research is development of aesthetically valuable surface ornamentation to make magnesium alloy sheet widely available in the field of design and craft. Through developing technique that makes fine embossed surface of magnesium sheet and thin coats of color ottchil on that, beautiful harmony of delicate metal texture and natural color of ottchil can be presented. firstly, surface treatment technique to make high adhesive strength with ottchil and effective method to make elaborate surface pattern was researched. The motif is cross-hatch pattern with '米’ shape. It was changed to a vector image and projected through light to magnesium alloy sheet which was corroded in dilute acid. Than, means of apply thin coats of color ottchil was researched. The process to reveal the metal texture through characteristic color of ottchil, and the color mixing effect through overlapping and juxtaposition of two different color were studied. This surface ornamentation is not only decorative but also effective to complement weak corrosion properties, so it can contribute to extend the range of usage of magnesium alloy sheets to various design and craft productions.
