High Temperature Tribological Behavior of Ball Milled Expanded Graphite/Iron Powders

Abstract:

A mixture of expanded graphite (EG) and iron powders was ball-milled in a high-energy mill. The milled EG/Fe powders were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The tribological behavior of the milled powders used as lubricating additive was investigated by using a tribo-tester. The results show that the milled powders used as lubricating additive have an obvious anti-friction effect, and the more large the applied temperature, the more marked the anti-friction effect.
