- Preparing method of metal-carbon composites for high speed slip-ring
The present invention relates to a method for manufacturing a metal-carbon composite for manufacturing high-speed slip rings. According to the present invention, the method comprises: (a) a graphite pulverizing step; (b) a graphite surface coating step; (c) a sieving step of securing uniform particles; (d) a kneading step of kneading metal-coated graphite particles and metal particles; (e) a molding step through isostatic pressing; (f) a part manufacturing step through sintering; and (g) a final part processing step through machining. Accordingly, due to uniform dispersion of carbon particles, electrical conductivity is increased and a coefficient of friction and electrical resistance are decreased, and thus the metal-carbon composite can be usefully used for a high-speed slip ring.
본 발명은 고속 슬립링 제조를 위한 금속-탄소 복합재료 제조에 관한 것으로, (a) 흑연의 입자화(pulverizing) 단계; (b) 흑연 표면 코팅(coating) 단계; (c) 균일한 입자 확보를 위한 분체(sieving) 단계; (d) 금속 코팅된 흑연입자와 금속입자와의 혼련(kneading) 단계; (e) 등압(Isostatic pressing)을 통한 부품 성형(molding) 단계; (f) 소결(sintering)을 통한 부품 제조 단계; 및 (g) 절삭(machining)을 통한 최종 부품 가공 단계; 를 특징으로 이루어져 탄소 입자의 균일한 분산에 의해 전기전도성을 증가시키고, 마찰계수 및 전기저항을 줄여주어 고속 슬립링에 유용하게 활용될 수 있다.
