摘要: 采用MM-200型摩擦磨损试验机对在干摩擦条件下3种硅纳米材料(纳米SiC、SiO2及Si3N4)与玻璃纤维混杂填充聚酰胺6(PA6)复合材料与45#钢对磨时的摩擦磨损性能进行了研究,并采用扫描电子显微镜对复合材料的磨损表面进行了观察。结果表明,3种纳米硅材料都能减小复合材料的摩擦因数,其中以纳米SiO2与玻璃纤维混杂效果最佳,纳米SiC、SiO2及Si3N4的最佳含量分别为3 %、5 %和3 %。纳米SiO2和纳米Si3N4能够提高复合材料的耐磨性,而纳米SiC会导致复合材料的磨损量增大。

Abstract: The friction and wear properties of polyamide 6 (PA6) composites filled with glass fiber (GF) and one of three nano-silicon-based particles were investigated using a MM-200 wear tester. The worn surfaces of the composites were examined through a scanning electric microscopy. It showed that the friction coefficients of the composites were reduced when GF and a silicon-based particle were filled in, and nano-SiO2 was the best. The optimal filler contents for the composites were 5 % SiO2, 3 % Si3N4 and 3 % SiC, respectively. Nano-SiO2 and nano-Si3N4 improved the anti-wear properties of the composites, while nano-SiC increased the wear mass loss of PA6 composites.
