The experimental tests of selected tribo-pair in three loading cycles were compared in this paper. Tests were performed with mineral transmission oil and ecological synthetic ester base oil, which were dropping by Gravity Force through the overhead part of measuring head of the laboratory testing device. The influence of factors (load cycle, lubricant) on the bearing shells and shafts was statistically verified by analysis of variance (ANOVA). The relevant differences between average values of each specimens were defined using Duncan`s multiple range test with a p-value of 0.05. Dynamically loaded tribo-pairs showed bigger mass losses and higher friction coefficients compared to the static cycle in conditions of the experiment, regardless of the lubrication method. This effect was even more significant in environment lubricated with mineral oil. Results confirmed that processes of dynamic loading play a significant role in evaluating selected parameters (wear, friction force, friction coefficient) tribological nodes of agricultural, forestry and other industrial machines.

“…As the chemical composition of olive oils may vary, it supposes the variety of interactions with materials even in the case of the same type of oils. For example, tribological tests of wear resistance properties of differently produced rapeseed oils show that unrefined rapeseed oil has better wear resistance as compared to that of refined oil [20]. In this study we explored the influence of different chemical composition and physical properties of olive oils produced from various districts in Morocco on their tribological performance and corrosion protection.…”

The influence of different chemical composition and physical properties of olive oils, produced from various districts in Morocco with various acidic numbers (from 1.76 to 18.01), on their tribological performance and corrosion protection has been investigated. The chemical composition was determined by means of IR, 1H and 13C NMR spectroscopy. The investigated olive oils show small quantitative and qualitative differences between each other (the amount of free fatty acids and the composition of fatty acids in triglycerides). The spectroscopic data let us unambiguously determine in general that the main fatty acids in oils are saturated palmitic and/or stearic acids, unsaturated oleic and linoleic acids except linolenic acid. The oxidation stability of oils was estimated. The contact angle measurements and electrochemical impedance spectroscopy data show that all films of olive oils on the surfaces of steels are porous; therefore, the values of corrosion inhibition efficiency are relatively low and ranged from 57 to 75%. The variations of friction coefficients and their mean values, the wear of steel covered by olive oils were estimated. The oils with the highest oxidation stability also show better lubricating properties.

“…The second direction of development is to use green lubricants (for example, green oil, ionic liquid bio-lubricant, and biopolymers) made of natural materials; in addition to reducing the use of petroleum oil, this method enables the materials to be reused and recycled. Examples of such oils include natural vegetable oil [ 12 , 13 ], rice bran oil [ 14 ], rapeseed oil [ 15 ], and coconut oil [ 16 ]. Natural oils display favorable scalability; research has shown that with the addition of appropriate green additive(s), natural lubricating oils can exhibit lubrication properties identical to those of petrochemical lubricants [ 13 , 17 , 18 , 19 ].…”

Hydroxypropyl methylcellulose (HPMC) is a biopolymer that is biodegradable, environmentally friendly, and bio-friendly. Owing to its unique chemical structure, HPMC can reduce the coefficient of friction (COF) and frictional wear and thus possesses excellent lubrication properties. HPMC has good dissolvability in specific solvents. The present research focuses on the reversible dissolution reaction subsequent to the film formation of HPMC, with a view to the healing and lubrication properties of thin films. Raman spectroscopy was used to test the film-forming properties of HPMC and the dissolution characteristics of various solvents. In this study, the solvents were water, methanol, ethanol, and acetone. The results showed that the HPMC film had the highest dissolvability in water. The ball-on-disk wear test was used to analyze the lubrication properties of HPMC, and the results showed that HPMC had the same COF and lubrication properties as the original film after being subjected to the water healing treatment. The HPMC film can be reused, recycled, and refilled, making it an ideal lubricant for next-generation ecotribology.
