Moringa and Graphite as Additives to Conventional Petroleum-Based Lubricants

Many researches are focused on the tribological performances of pure vegetable oil in order to replace conventional mineral engine oils. This work investigates influence local moringa (noted VO) lubricants formed from a blend dodecane and graphite particles at ambient temperature. In first part, reduction about 50% friction properties is observed when adding small amounts (VO), which intended be used as bio-base performance additive lubricant formulations. The their blends with graphite, generally employed solid additive, showed an adsorption effect fatty acid molecules. more promising results were obtained for containing 2 w% VO. Physicochemical characterizations tribofilms evidence good antiwear lubricant.
