... the friction force in many different transversely isotropic coatings, including MoS2, NbSe2, InSe2, GaSe2, GaS, and graphite. Having simulated 540 different operating conditions by varying load, geometry, and solid lubricant type, they arrived at the following normalized relationship for friction force: F...

... with the varied proportion of friction modifiers in the range between 1 vol% and 20 vol%. The ratio of solid lubricants determines the ideal friction coefficient of the Cu-based sintered composites. The optimum friction coefficient of 0.3–0.5 was obtained for the 5 vol%–10 vol% friction modifiers. Excess solid...

... nontextured counterpart. The tool surface covered with copper reduces the chip deformation coefficient by 7.7%. Copper not only reduces surface defects but also forms a lubricating film during cutting operations, thereby serving as an effective solid lubricant. The synergistic interaction between texture...

... affects the COF and wear-rate under both sliding conditions. While the presence of Ag as a solid lubricant is anticipated to improve tribological properties, its incorporation leads to reduced retention of Al 2 O 3 within the sprayed coating. Consequently, the overall tribological performance hinges...

In this work, graphite, molybdenum disulfide (MoS 2 ), and tungsten disulfide (WS 2 ) solid lubricant coatings were prepared on aluminum-based piston skirts, respectively. The friction...

... lubricants have recently aroused significant interest due to their defined friction and wear properties. Despite enormous efforts on solid lubricants, their important contributions to coatings, bulk materials, oil/grease, and super-lubricity have not yet been fully evaluated. This paper discusses in detail...

...), the main chemical component of serpentine, is necessary. In order to further improve the tribological performance of serpentine as a lubricant additive, scholars have obtained good results by combining serpentine with different kinds of solid lubricants, such as rare earth compound and MoS 2 [ 19 , 20...
