摘要
采用纳米级金属及金属氧化物Cu,Al,ZnO,Fe2O3等填充聚四氟乙烯(PTFE),并将其制备成试样.干摩擦条件下在MM-200磨损试验机上,对其进行摩擦学性能研究.试验表明:4种纳米颗粒改性PTFE使得耐磨性比纯PTFE有明显提高,而且其摩擦因数比纯PTFE的摩擦因数低.
The friction and wear properties of PTFE composites with nano-Cu, nano-Al, nano-ZnO, nano-Fe2O3 silding under dry friction condition were studied by using a MM-200 ring-block wear tester, and then the wear mechanisms of PTFE composites filled by the nano-materials were discussed. Friction and wear results show that the friction coefficient of the nano-particles filled PTFE composites are lower than the pure PTFE; And the anti-wearing properties of the nano-particles filled PTFE composites are well than the ...
