LASER를 활용한 도자기 문양디자인 방법에 관한 연구

Abstract

Ceramics decoration techniques which can be utilized in the industrial ceramics field that should consider productivity have limits. This study suggests the method which selectively melt glaze by utilizing laser as the decoration technique which satisfies design factors and productivity. The possibility of pattern decoration on the ceramics surface was studied by utilizing Universal’s VLS 6.60 model which uses CO2 gas as an active medium of light amplification. The method which selectively melt glaze to keep corrosion resistance of ceramics, its advantage, and at the same time apply patterns to the surface was calculated as the research direction. As for the basic experiment, 46J to 52J energy was checked as the most effective conditions by analyzing the changing process of glaze surface according to laser output by an optical microscope and a scanning electron microscope. It has found that fine cracks increase on the boundary melting surface when output is investigated to be excessive and creation of pattern was not arranged as insufficient output does not provide the quantity of heat which is necessary for melting glaze. Each sample was made by the vector and raster methods as the laser irradiation conditions checked through the basic experiment and the result was analyzed. The vector method specialized in line processing can create patterns with high readability because of the fast and uniform irradiation quantity. However, the temperatures which rapidly change in partial regions have found to cause residual carbon and changes of pattern colors. The Raster method checked the possibility to can extend ceramics’ unique esthetics by creating uneveness and blow hole in the selective areas. It suggested the possibility to apply the selective method which melts glaze by utilizing laser to new ceramics decoration techniques as the decoration techniques which can be applied to the ceramics industry.
