Green oil additive g-C₃N₄: a feasible strategy to enhance the tribological properties of DLC film

Functionalised h‐BN as an effective lubricant additive in PAO oil for MoN coating sliding against Si3N4 ball

“…Adding lubricant additives of nanoparticles in the base oil is an effective technique for achieving improved tribological properties for machinery component. It is an more effective strategy by constructing a lubrication system using suitable lubricants and hard coatings as friction interfaces to reduce friction and wear 1‐3,19‐22 . For instance, Liu et al 2 achieved extreme wear resistance and friction reduction in a solid‐liquid composite lubrication system constituted with g‐C 3 N 4 nanosheets as the lubricating oil additives and Ti‐DLC film as the rubbing surface.…”

“…Currently, two-dimensional (2D) materials such as graphene, black phosphorus, MoS 2 , and their derivatives have been demonstrated to be potential lubricant additives due to their attractive layered structure. [1][2][3][4][5] Particularly, hexagonal boron nitride (h-BN), a typical layered 2D material, has unique structure in which van der Waals forces exist between two covalently bonded sheets. Accordingly, h-BN exhibits superior mechanical strength and can easily shear at the contact interfaces as employed as lubricant additives.…”

“…Applying lubricant additives has been widely considered as a convenient way to enhance tribological performances for the lubricating system. Currently, two‐dimensional (2D) materials such as graphene, black phosphorus, MoS 2 , and their derivatives have been demonstrated to be potential lubricant additives due to their attractive layered structure 1‐5 . Particularly, hexagonal boron nitride (h‐BN), a typical layered 2D material, has unique structure in which van der Waals forces exist between two covalently bonded sheets.…”

Zeng et al 19 revealed that the addition of nano-BN in poly-alpha-olefin (PAO) leaded to the superlubric state for Si 3 N 4 -ball/DLC-disc contact.…”

В то же время, относительно структуры NEM в литературе встречаются разночтения.…”
