Effect of Cr Addition on Properties and Tribological Behavior at Elevated Temperature of Boride Layers Grown on Borosintered Powder Metallurgy Alloys
(Korean Institute of Metals and Materials, 2022)
This study focused on chromium addition (0 wt%, 3 wt%, 6 wt%, 9 wt% and 12 wt%) on the boride layer formation, microhardness, fracture toughness and elevated temperature friction and wear behaviour of alloys formed by ...
Effect of boronizing on microstructure, high-temperature wear and corrosion behavior of additive manufactured Inconel 718
(Elsevier, 2022)
In this study, Ni-based Inconel 718 coatings were additively manufactured on the surface of AISI H13 work tool steel by electro-spark deposition (ESD). Some of the electro-spark deposited samples were boronized at 1000 ? ...
Effect of the boriding environment on the wear response of laser-clad AlCoCrFeNi high entropy alloy coatings
(Elsevier, 2022)
Laser-clad AlCrFeCoNi high entropy alloy (HEA) coatings, produced on the surface of AISI 316 L stainless steel, were pack-borided at 1000 °C for 4 h in open air, high-purity Ar and vacuum environments. The HEA, which had ...
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 ...
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, ...
