    摘要:

    本文研究了銅-30vol%石墨、銅-30vol%二硫化鎢和銅-30vol%二硫化鉬三種銅基自潤(rùn)滑復(fù)合材料的抗電弧燒蝕性能。結(jié)果表明：石墨熔點(diǎn)較高,在電弧放電瞬間主要以氧化的形式損耗,而二硫化鎢和二硫化鉬則會(huì)在電弧放電造成的高溫下發(fā)生熔化甚至與銅基體發(fā)生化學(xué)反應(yīng),所以銅-30vol%石墨復(fù)合材料的抗電弧燒蝕性能要優(yōu)于銅-30vol%二硫化鎢和銅-30vol%二硫化鉬復(fù)合材料。銅基自潤(rùn)滑復(fù)合材料的電弧燒損機(jī)制主要有材料的氧化、熔化飛濺、內(nèi)部化學(xué)反應(yīng)以及疲勞脫落。

    Abstract:

    In this study arc erosion properties of Cu-30vol%gaphite, Cu-30vol%WS2 and Cu-30vol%MoS2 composites were investigated. The results demonstrated that graphite cannot beSmelted and mainly lost in the form of oxidation during the arc discharge process because of its extremely high melting point. In contrast, WS2 and MoS2 were melted and even reacted with Cu matrix due to the high temperature caused by arc discharge. Therefore, the arc erosion resistance of Cu-30vol%gaphite composite was better than those of Cu-30vol%WS2 and Cu-30vol%MoS2 composites. The main arc erosion mechanisms of Cu-based self-lubricating composites were found to be oxidation, melting, ejecting, internal chemical reaction and fatigue peeling.
