Characterization and Diffusion Kinetics of Silicon on AISI D2 Steel
Silicon, 2023 This paper presents the simultaneous influence of two different activators (NH4Cl and NaF) on the kinetic evolution during siliconising of steel. The AISI D2 tool steel surface was coated by pack siliconising through the growing of silicon on the surface. Pack siliconising was accomplished by employing a mixture of powders of Si 12 wt% + NH4Cl 0.5 wt% +

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 ...

Pack Siliconizing Optimization of AISI D2 Tool Steel
Silicon, 2022 AbstractThe paper describes the pack siliconizing optimization procedure for AISI D2 tool steel. Pack siliconizing was performed by employing different treating temperatures (falling in the range 650–950 °C) and times (falling in the range 2–4 h). The siliconizing atmosphere was obtained through silicon (at 12 wt.%) with the addition of different ...

Effect of Post-Heat Treatment on the AISI M4 Layer Deposited by Directed Energy Deposition
Metals, 2020 Currently, high-speed steel (HSS) powders are deposited locally on a metal surface through direct energy deposition (DED) onto hardface tool steel. Although the HSS powder enhances the hardness and the abrasion resistance of a metal surface, it makes the

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 ...
