    摘要:

    經(jīng)過(guò)2, 5, 7, 9 kV放電電壓作用后，分析了受電弓材料Ti3AlC2和Cu-Ti3AlC2的電弧燒蝕性。Cu-Ti3AlC2材料的電弧壽命和擊穿電流都比Ti3AlC2的短。高速攝影機(jī)用來(lái)記錄兩種材料的電弧形態(tài)。Ti3AlC2上的電弧要比Cu-Ti3AlC2的電弧更加集中，伴隨著更多的液滴飛濺。采用掃描電鏡（SEM）觀察了被侵蝕的兩種材料表面情況。和Cu-Ti3AlC2的表面相比，Ti3AlC2的表面更加不均勻，表面覆蓋有“孔洞”，“顯微裂紋”和“飛濺物”。計(jì)算了不同電壓下的電弧能量，結(jié)果表明，在相同電壓下，Cu-Ti3AlC2材料的電弧能量小于Ti3AlC2材料。采用拉曼光譜法測(cè)定了被燒損樣品表面的成分。實(shí)驗(yàn)結(jié)果表明，Cu-Ti3AlC2更適合于做受電弓材料。

    Abstract:

    The electrical ablation properties of typical pantograph materials Ti3AlC2 as well as Cu-Ti3AlC2 were analyzed under 2, 5, 7, 9 kV. The arc life of Cu-Ti3AlC2 was shorter than that of Ti3AlC2. The breakdown current showed the same condition. High speed camera was employed to record the arc morphologies of the two materials. The arc on Ti3AlC2 was more concentrated than that of Cu-Ti3AlC2, accompanying with much more droplet splashes. The eroded surfaces of the two materials were observed by Scanning Electron Microscopy (SEM). Comparing to the eroded Cu-Ti3AlC2, Ti3AlC2 surface was more uneven, covered with "holes", "microcracks", "splashes". The arc energy at different voltages were calculated. It was shown that the arc energy of Cu-Ti3AlC2 material was less than that of Ti3AlC2 material under the same voltage. Raman spectrometer was carried out to determine the compositions of the eroded surfaces. Summarizing the experimental results, it could be found out that Cu-Ti3AlC2 is more suitable for pantograph material.
