A lubricant composition includes a base lubricant and a plurality of lubricant additive molecules functioning as precursor molecules to induce tribopolymerization and forming in situ protective tribofilm with desirable robustness and low shear resistance. Each lubricant additive molecule includes one or more surface-active groups attractable to target surface, and a carbon containing component operable connected to the one or more surface active groups. The carbon containing component comprise a carbon ring structure having a high ring strain that is metastable and activatable with a ring-opening reaction. A less stable carbon ring structure is more readily activated to the intermediate state, preferable to form more active fragments. Increasing the adsorption strength further is beneficial to prolonging the residence time of additive molecules on the target surface, thereby facilitating the dissociation of molecules and subsequent polymerization.

A composition for lubricating and/or descaling in the hot processing of metals includes a solid mixture containing the following constituents: (a) 20 to 60% by weight of condensed alkali phosphate, (b) 10 to 40% by weight boron compound selected from borosilicate glass, boric acid, boric acid salt, or a mixture thereof, (c) 10 to 30% by weight alkali or alkaline earth sulphates, (d) 5 to 25% by weight fatty acid, fatty acid salt, or a mixture thereof. The sum of the constituents (a) and (b) constitutes at least 50% by weight of the mixture and the sum of the constituents (a) to (d) constitutes at least 85% by weight of the mixture.

A lubricating oil composition can include a major amount of an oil of lubricating viscosity and a minor amount of an alkaline earth metal phenol-based detergent. The lubricating oil composition can further have a BN of greater than 140 mg KOH/g, and further wherein the marine diesel cylinder lubricating oil composition is substantially free of unsulfurized tetrapropenyl phenol and its unsulfurized metal salt.
