Abstract: 본 발명은 티탄합금의 표면경화처리하는 방법에 관한 것으로서, 더욱 상세하게는 엔지니어링 부품으로서 다른 금속부품과의 미끄럼 부재로 사용되는 티탄 또는 티탄합금재에 대한 표면경화처리시 이산화탄소 및 일산화탄소를 사용하는 새로운 산화방식을 채용하므로서, 종래와 비교할 때 경제적이면서도 스케일제거공정이 필요없는 간단한 공정으로 티탄합금의 표면을 경화처리 시킬 수 있도록 하는 개선된 방법에 관한 것이다.

Abstract: The insulating material is obtained by (1) mixing 65-80 wt.% of glass fiber (diameter = 10 μm, length = 50-75 mm) and 20-30 wt.% of polyester (length = 70-100 mm), and then carding it, (2) adding 10-30 wt.% of powder resin into 100 wt.% of the mixture and impregnating it, (3) coating the impregnated with nonwoven fabric, and (4) heat pressing at 200-230 deg.C. The powdary resin is ABS or epoxy resin. The insulating material has an improved heat resistance, tensile strength, weather resistance and chemical resistance, and is useful for automobile hoold.
