摘要：
A tribological comparison was conducted among micro-MoS2 (m-MoS2), platelet-like nano-MoS2, and spherical nano-MoS2 in lithium grease, lithium-calcium grease, and polyurea grease, respectively. Micro-MoS2 slightly improved the lubrication of the 3 greases. The 2 nano-MoS2 samples had obvious superiority over m-MoS2. The tribofilms produced by nano-MoS2 contained MoS2 and MoO3. However, the tribofilms with m-MoS2 did not contain Mo, or Mo only existed in the form of MoO3. The absence of MoS2 in tribofilms was the main reason for the poor lubrication of m-MoS2 greases. Moreover, the improved lubrication of the spherical nano-MoS2 greases than the platelet-like nano-MoS2 ones was ascribed to the lubricating superiority of the spherical structure to the platelet-like one.
