| Shrnutí: | Title screen The densification of B4C/ultra-high molecular weight polyethylene (B4C/UHMWPE) composite is difficult, especially when there is a large B4C content. In the current work, B4C/UHMWPE composites with 75 vol%B4C were successfully prepared by spark plasma sintering, and their densification process and microstructure were carefully studied. Results show that the horizontal-ball-milled powder contains angular B4C particles, irregular UHMWPE particles and fine particles. The rapid densification occurs in a special stage, with the starting temperature between 110oC and 140oC, and the ending temperature around 200oC. The relative density of the composites made from horizontal-ball-milled powder varies from 87.79 % to 94.37 %. When B4C content is 75 vol%, the composite has the highest Shore hardness. The planetary-ball-milled powder contains agglomerates of B4C and UHMWPE, strip-like particles and small B4C particles. Planetary ball milling has little effect on densification temperatures, but the prepared composites have more uniform microstructure, the samples are easier to be polished, and the relative density is greatly increased to 99.53 %. All the prepared composites are composed of B4C, UHMWPE and a small amount of impurities (C, B2O3, ZrO2, Fe-Cr-Al-Si). Planetary-ball milling increases the volume content of the orthorhombic UHMWPE. Ultrasonic assisted compacting further helps the closely stacking of powder particles and further promotes the densification process of the composite Текстовый файл AM_Agreement |
