摘要:
The tribological properties of soybean oil (SO) with different molybdenum disulfide (MoS2) additives (hollow nanosphere, nanoplatelet and microplatelet) were investigated. MoS2 hollow nanospheres remarkably improved the tribological properties of SO. SO with MoS2 hollow nanospheres decreased abrasive plowing and changed the main wear pattern on the steel friction surfaces into chemical corrosion. The MoS2 hollow nanospheres easily entered the contact region than the other MoS2 particles to lubricate the friction pair because of its good dispersibility in SO. The tribochemical reactions among MoS2 hollow nanospheres, SO and friction material produced a lubricating film composed of MoO3, Fe-2 O-3, carbon containing compounds. Thus, the MoS2 hollow nanospheres have potential lubricating applications with SO. By contrast, MoS2 nanoplatelet and microplatelets had lesser effects on the lubricating effect of SO. The MoS2 nanoplatelets, even with its smaller size and more active chemical properties, had more difficulty in entering into the contact region because of its low dispersibility in the base oil.
