Abstract

270∼350km/H의 속도범위내에서 고속주행을 하는 전기차량의 팬토그래프용 접판으로서 실용에 제공할 수 있는 접전슬라이더용 내마모소결합금은, 중량비로, 단체 Cr8∼25%, 금속황화물 3∼9%, 질화붕소(BN)0.1∼4%, 인(P) 1%이하, 납(Pb) 3∼8%, 나머지부가 Fe로 이루어지는 각 원료분말을 혼합해서 압축성형한 후, 비산화 분위기중 혹은 환원분위기 중에서 소결하여 얻어진다. 납을 배합하지 않고, 금속황화물과 BN의 혼합비를 중가시키는 것에 의해서, 압축성형이 개선된다. BN온 고온시에도 양호한 윤활성능을 나타내지만, 금속분말과의 습윤성이 나빠서 금속과의 혼합물의 압축성형이 곤란하다. 그러나 BN과 금속황화물을 병용하면, 압축성형성이 개선되며, 또 600℃정도까지는 금속황화물과 BN의 윤활특성을 합산하여 활용하고, 600℃∼1000℃의 범위는 BN이 갖는 양호한 윤활성능을 활용해서, 270∼350km/H의 고속주행에 따라 고온하에서도 양호한 윤활성과 내마모성을 발휘할수가 있다.The wear-resistant bond alloy for contact sliders, which can be practically provided as a contact plate for pantographs of electric vehicles running at high speeds within the speed range of 270 to 350 km / H, has a weight ratio of single Cr8 to 25% and metal sulfides 3 to 3 9%, boron nitride (BN) 0.1 to 4%, phosphorus (P) 1% or less, lead (Pb) 3 to 8%, and the rest of the raw material powder consisting of Fe mixed and compression molded, and then in a non-oxidizing atmosphere Or obtained by sintering in a reducing atmosphere. Compression molding is improved by increasing the mixing ratio of metal sulfide and BN without compounding lead. Although the BN temperature shows good lubricating performance even at high temperatures, it is difficult to compress the mixture with the metal because of poor wettability with the metal powder. However, when BN and metal sulfide are used together, compressibility is improved, and the lubrication properties of metal sulfide and BN are summed up to about 600 ° C, and the range of 600 ° C to 1000 ° C utilizes good lubrication performance of BN. High lubrication and wear resistance can be achieved even at high temperatures due to high speed of 270 ~ 350km / H.
