Abstract

새도우 마스크 표면에 산화피막을 형성시켜 산화, 열흡수 및 노광빔 등의 난반사를 방지시키기 위한 흑화처리 공정에 있어서 그 새도우 마스크를 안착시켜 가열로 내부로 공급하는 메쉬벨트용 합금소재에 대하여 개시 한다. 상기 합금의 고온내식성을 향상시키는 방법으로서, 철을 베이스로 한 금속에 알루미늄을 3wt%첨가시킴으로써 그 철 베이스 합금의 표면에 치밀한 알루미나 산화막을 형성시켜 고온 내식성을 향상시킨다.The present invention relates to an alloy material for mesh belts that forms an oxide film on a shadow mask surface to prevent diffuse reflection such as oxidation, heat absorption, and exposure beam, and to which the shadow mask is seated and supplied into a heating furnace. As a method of improving the high temperature corrosion resistance of the alloy, by adding 3 wt% of aluminum to an iron-based metal, a dense alumina oxide film is formed on the surface of the iron base alloy to improve high temperature corrosion resistance.
