聚乙二醇黄原酸修饰水溶性铜纳米微粒的制备及其摩擦学性能研究
|
摘要
采用聚乙二醇黄原酸为修饰剂,通过原位表面修饰技术制备得到粒径分布均匀,在水溶液中具有良好分散性及稳定性的铜纳米微粒。将所得聚乙二醇黄原酸修饰铜纳米微粒作为水基添加剂考察其抗腐蚀性能及摩擦学性能。结果表明:聚乙二醇黄原酸修饰铜微粒的加入有效提高了水基润滑剂的承载能力和极压性能,当铜微粒的质量分数为2%时,水基润滑剂的最大无卡咬负荷和烧结负荷分别增加到了274 N和7 840 N;同时聚乙二醇黄原酸修饰铜纳米微粒还可有效提高水基润滑剂的抗腐蚀性能。对磨斑表面进行的EDS及XPS表征显示,磨斑表面形成了含有铜及Fe S的边界润滑膜,该润滑膜能有效减少或避免摩擦表面直接的钢/钢接触,降低摩擦接触压,明显提升水基润滑剂的摩擦学性能。
Copper nanoparticles with uniform size distribution and good dispersion in aqueous solution were prepared by in situ surface modification technique using polyethylene glycol xanthate as modifier. The tribological properties and corrosion resistance properties of as-synthesized Cu nanoparticle as water-based additive were investigated with a four-ball machine. The results show that the as-synthesized copper nanoparticles can significantly improve the carrying capacity and extreme pressure property of distilled water,and the maximum non-seizure load and weld point of distilled water are increased to 274 N and 7 840 N respectively when the mass fraction of copper particles is 2%. The as-synthesized copper nanoparticles can also significantly improve the corrosion resistance of the water-based lubricant. By characterization of the surface of the wear scar by EDS and XPS,it is found thta a protective and lubricious film composed of Cu and Fe S is formed on steel sliding surfaces lubricated by distilled water containing Cu nanoparticles. The lubricating film can effectively reduce or avoid the direct steel/steel contact between the friction surface and obviously improve the tribological properties of the water-based lubricant.
