Determination of fracture toughness of boride layers grown on Co1.21Cr1.82Fe1.44Mn1.32Ni1.12Al0.08B0.01 high entropy alloy by nanoindentation
(Elsevier, 2022)
Multiphase boride layers consisting of (CoFe)2B, (Fe0.4Mn0.6)B, Cr2Ni3B6 and (Cr0.4Mn0.6)B were formed on the surface of Co1.21Cr1.82Fe1.44Mn1.32Ni1.12Al0.08B0.01 high entropy alloy by powder-pack boronizing at 900 °C, 950 ...
Microstructural characterization, boriding kinetics and tribo-wear behavior of borided Fe-based A286 superalloy
(Elsevier, 2022)
Iron-based superalloys are alloys produced for use in corrosive environments as an alternative to high-cost nickel-based superalloys. However, their average strength and hardness, attributed to their austenitic structures, ...
Microstructural and Tribological Behavior of Pack-Borided Ni-Based Hastelloy C-276 Superalloy
(Springer, 2022)
Although the toughness and corrosion resistance of Ni-based superalloys are high due to their face-centered-cubic structure, their surface hardness and, thus, wear resistance are not satisfactory. The boriding process is ...
Investigation into the influence of boronizing on the wear behavior of additively manufactured Inconel 625 alloy at elevated temperature
(Springer, 2023)
Directed energy deposition (DED) technology is a cost-effective additive manufacturing method widely used in the production of complex-shaped parts made of various engineering alloys as well as superalloys due to its ...
A new approach to improve some properties of wire arc additively manufactured stainless steel components: Simultaneous homogenization and boriding
(Elsevier, 2023)
Arc-directed energy deposition (Arc-DED), also commonly referred to as wire arc additive manufacturing (WAAM), is a cost-effective 3D metal additive manufacturing process in which large metallic parts can be produced due ...
A response surface study on the grown behavior and some mechanical properties of niobium carbide coatings
(World Scientific, 2023)
In this study, response surface methodology was used to examine the effects of temperature and time on the development of niobium carbide coatings on AISI D3 steel. The effect of niobizing temperature (900-1100C) and period ...
Effect of boriding on high temperature tribological behavior of CoCrMo alloy
(Elsevier, 2023)
In the present work, CoCrMo alloy surfaces were subjected to powder-pack boriding at 950 & DEG;C for 5-hour and 7 -hour treatment periods. The obtained boride layers were characterized with scanning electron microscopy, ...
Niobium Carbide Coatings Grown on Cold Work Tool Steel AISI D3 by Thermomechanical Processing: Characterization, Wear and Corrosion Behaviors
(Springer, 2023)
In this study, niobium carbide (NbC) coatings were grown on AISI D3 cold work tool steel via thermoreactive diffusion (TRD) at 900, 1000 and 1100°C for 2, 4, and 6 h. The microstructures and phase formed, the surface ...
Sliding Wear and Friction Performance of Pack-Borided Co–28Cr–6Mo Alloy in Physiological Lubricants
(Springer, 2023)
The role of bovine calf serum (BCS) related to the functional performance of synovial fluid on the tribological behavior of borides grown on cobalt-28chromium-6molybdenum (Co-28Cr-6Mo) alloy used in orthopedic prostheses ...
Effect of boriding on tribocorrosion behaviour of HSLA offshore mooring chain steel
(Elsevier, 2023)
This study explores the transformative potential of boriding to enhance the tribocorrosion resistance of mooring chain steel for offshore environments. The boride layers formed at various temperatures (800 degrees C, 900 ...
