摘要：

Herein, the porous graphite carbon nanospheres loaded with corrosion resistance (MBT@PCNs) were fabricated by carbonizing hypercrosslinked polystyrene nanospheres at 2450 degrees C, and then loaded and bonded with corrosion inhibitor 2-mercaptobenzothiazole (MBT) via the hierarchical porous structure of PCNs and grafting polydopamine layer. Porous carbon nanospheres (PCNs) are highly graphitized at ultrahigh carbonization temperature of 2450 degrees C, which is helpful to improve the wear resistance of 500SN due to the weak interlaminar shear force. Moreover, the MBT@PCNs have a sustained-release performance for corrosion inhibitor MBT. MBT molecule can be adsorbed on the substrate surface to achieve good anti-corrosion properties. Hence, MBT@PCNs can effectively enhance the anti-friction and anti-wear performance of 500SN under the combined effects of ball bearing, filling, and protective film.
