摘要: The tribological behavior of the CoCr28Mo/CoCr28Mo pair was studied using pin-on-disc tribometer. Four bio-lubricants were retained including pure sesame oil, nigella physiological solution (0.9% NaCl) and Hyalgan®. Hyalgan® is a sodium hyaluronate (20 mg/2 mL) pharmaceutical intra-articular injection used, in this study, as reference. Coefficient Friction (CoF) wear rate (K) CoCr28Mo computed after tests. efficiency vegetable oils with regard to their chemical composition structure compared Hyalgan. It found that, use enhanced significantly pair. obtained results correlated namely Unsaturations Number (UN) fatty acids constituting oil. Microscopic characterization pins discs conducted mechanism discussed.
