Friction and Wear Behavior of Titanium Complex Grease with Admixture Base Oil

Most of the lubricants are made of mineral oil which has bad biodegradability, and, hence, seriously contaminate the environment. To minimise the lubricants’ impact on the environment, this research developed a new type of lubricant, titanium complex grease. Its base oil is the admixture of vegetable oil and mineral oil. Its production method and experimental results are presented in this paper. The friction, wear and physical-chemical properties of the grease were investigated. The morphology of wear scar of steel ball was observed using the sweep electron microscope. The results obtained contribute to the further development of environmentally friendly lubricants.
