    • Lignin composite ionic liquid lubricants with excellent anti-corrosion, anti-oxidation, and tribological properties
    Authors: Chaoyang, Zhang; Zhiquan, Yang; Qing, Huang;  Advisor: -;  Co-Author: - (2022)

    A new type of lubricating material (BTA-P4444-Lig) was synthesized by combining lignin with tetrabutylphosphorus and benzotriazole. The tribological properties, corrosion resistance, and anti-oxidation properties of BTA-P4444-Lig as a lubricant were investigated. The lubricating material exhibits excellent friction reduction and wear resistance, as well as good thermal stability and excellent oxidation resistance. Mechanistic analysis reveals that the active elements N and P in the lubricating material react with the metal substrate, and the reaction film effectively blocks direct contact between the friction pairs, affording excellent friction reduction and wear resistance. At the sa...
