    摘要:

    采用高能行星球磨機(jī)在純銅基體表面制備了具有一定厚度的W顆粒增強(qiáng)復(fù)合層。采用SEM、EDS、XRD和顯微硬度測試等分析測試技術(shù)分析了不同球磨時間下得到的復(fù)合層的沉積過程及復(fù)合層的顯微組織及力學(xué)性能，并對復(fù)合層的形成機(jī)理進(jìn)行了探討。結(jié)果表明，顆粒增強(qiáng)復(fù)合層的厚度在一定球磨時間內(nèi)達(dá)到最大值，之后不再隨著球磨時間的增加而增加。然而適當(dāng)延長球磨時間能改善復(fù)合層內(nèi)增強(qiáng)顆粒和基體間的結(jié)合強(qiáng)度，并在一定程度上改善W層的致密度。

    Abstract:

    High-energy planetary ball mill was applied to fabricate W particle reinforced composite layer in the surface of pure copper substrate. Scanning electron microscopy (SEM), X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDS) and micro-hardness test technique were used to investigate the microstructure and mechanical properties of the coatings prepared at different milling time, and then the mechanism of the formation of the coatings were studied. The results showed that the thickness of the particle reinforced layer reached the maximum within a certain milling time at the selected milling parameters. However, the bongding between reinforcing particles and substrate could be enhanced through appropriate extension of milling duration, which would simultaneously facilitate the densification in the composite layer.
