Effect of Lubricant Formulations on the Tribological Performance of Self-Mated Doped DLC Contacts: a review

Effect of ZnDTP triboflim's morphology on friction behaviors of DLC coatings: Tribofilm characterization by 3D scanning electron microscope observation

“…ZnDPT tribofilm formation on DLC surfaces has been investigated extensively. Some research reported no tribofilm formation on the DLC coatings (Kalin et al, 2004) while others reported that tribochemical interactions of ZnDPT with DLC coatings result in the formation of a tribofilm with either a patchy-like or pad-like structure (Zahid et al, 2015). Aboua, Umehara, Kousaka, Tokoroyama, Murashima, Tasdemir, Mabuchi and Higuchi, Journal of Advanced Mechanical Design, Systems, and Manufacturing, Vol.12, No.7 (2018) Investigation by FESEM revealed that some tribofilm were present at the surface of disk samples investigated in this work after the tribological tests in PAO + ZnDTP oil.…”

Superlubricity of hydrogenated carbon films in a nitrogen gas environment: adsorption and electronic interactions at the sliding interface

“…Because of their unique physical, mechanical, and tribological properties, carbon-based lms have been used as solid lubricants in a broad range of applications from microelectromechanical systems (MEMS) to macro-scale mechanical components, and they have attracted much attention from academic and industrial researchers. [1][2][3] The design of carbonbased lms with superlubricity and the study of their tribological mechanisms have been popular research topics. 4,5 The different preparation methods and deposition conditions used to form amorphous carbon lms lead to different atomic bond congurations (e.g., C-H, C-C, sp 2 , or sp 3 ) and different bond proportions in these lms, which further determine the differences in their physical and chemical properties.…”
