【摘要】：近些年來,碳化物衍生碳以其獨(dú)特的性能被廣泛應(yīng)用在氣體存儲、超級電容器、催化劑載體和摩擦涂層等方面.鹵化法以成本低、制備工藝簡單等特點(diǎn)成為制備衍生碳涂層的熱點(diǎn).本文以SiC陶瓷基體為前驅(qū)體,通過高溫氯化處理工藝在SiC表面制備碳化物衍生碳涂層,并研究了反應(yīng)溫度與其摩擦學(xué)性能之間的關(guān)系.研究結(jié)果表明:在1 175℃下保溫2 h所制備的SiC-CDC涂層表面光滑平整、硬度最高、且與基體的結(jié)合強(qiáng)度最好.此時SiC-CDC涂層的干摩擦系數(shù)最小,耐磨性最強(qiáng),具有良好的摩擦學(xué)性能.氯氣刻蝕反應(yīng)制備SiC-CDC涂層可為工業(yè)上應(yīng)用衍生碳涂層提供理論和技術(shù)支持.
[Abstract]:In recent years, Carbide derived carbon has been widely used in gas storage, supercapacitors, catalyst carriers and friction coatings due to its unique properties. Halogenation has become a hot spot in the preparation of derived carbon coatings because of its low cost and simple preparation process. Carbide derived carbon coatings were prepared on the surface of SiC by chlorination at high temperature. The relationship between reaction temperature and tribological properties was studied. The results show that the surface of SiC-CDC coating prepared at 1 175 鈩，
