Development and Characterization of Blue-Colored Mg2Si-Based Recycled Alloys Using Scrap Light Metals

Currently, major issues in the mobile and information and communications technology industries are consumer demands stimulated by emotion and environmental pollution issues. In the case of such consumer demand, many companies are using a demand increase model that involves the application of success stories through the convergence of design and technology, and a significant improvement has been realized. The environmental pollution caused by various dyes or resins used to realize a specific color of metal exterior materials to stimulate consumer sensibility has reached a serious level. In this study, we tried to minimize the environmental pollution that occurs due to external painting by realizing the color for the metal itself rather than through an external color coating. In addition, in the case of metal materials, the desired metal atomic ratio was similarly realized by utilizing waste scraps of the Al alloy ADC12 and the Mg alloy AZ91 that had already been used, and a study on realizing a specific color of the metal itself through recycling was conducted. Through this study, we tried to solve both environmental and consumer demand issues through recycling of metal waste materials and development of ecofriendly metal materials that do not use paint or resin.
