Advanced Solid Lubrication with COK-47: Mechanistic Insights on the Role of Water and Performance Evaluation. [PDF]

Adv Sci (Weinh)
This study is the first to report the solid lubrication performance of the newly discovered Ti‐based MOF (COK‐47) powder. COK‐47 exhibits a remarkably lowest and most stable coefficient of friction compared to typical solid lubricants. The lubrication mechanism involves water molecules from the air participating in tribochemical reactions, forming an ...

Microstructural and Mechanical Characterization of Ledeburitic AISI D2 Cold-Work Tool Steel in Semisolid Zones via Direct Partial Remelting Process

Journal of Manufacturing and Materials Processing, 2022
The success of the thixoforming process largely depends on the created microstructure, which must be globular in the liquid phase. The solid–liquid structural changes that occur on as-annealed D2 tool steel when it is subjected to the so-called DPRM are ...
