Anti-Friction Effect of Ball-Milled Expanded Graphite/Ni Mixture Used as Lubricating Additive
A mixture of expanded graphite (EG) and nickel was ball-milled in a high-energy mill. The ball-milled EG-Ni mixtures were characterized by X-ray diffraction and their anti-friction effects used as lubricating additive were investigated. The results show that the mixtures have an obvious anti-friction effect. The effect is related with the crystallization degree of the milled EG depending on the milling time, the higher the crystallization degree, the higher the anti-friction effect.
