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 ...
Powder-pack boronizing of CoCrFeNiAl0.5Nb0.5 HEA: Modeling of kinetics, microstructural, mechanical, and tribological characterizations
(Elsevier, 2022)
This study is dedicated to the detailed investigation of boronization kinetic, microstructural, mechanical, and wear properties of high entropy alloys (HEAs) considering their sluggish diffusion effect properties. A ...
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, ...
Titanium carbide coating to improve surface characteristic, wear and corrosion resistance of spheroidal graphite cast irons
(Elsevier, 2022)
In this study, titanium carbide (TiC) coatings were grown on the surface of a spheroidal graphite cast iron (SGI) via thermo-reactive diffusion (TRD) using powder-pack processing at 800 °C, 850 °C and 900 °C for 4 h. The ...
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 ...
Wire electric discharge machining and its effect on the surface finish of HfNbTaTiZr refractory high-entropy alloy
(Springer, 2023)
Refractory high-entropy alloys (RHEAs) have high strength and hardness but limited plasticity at room temperature, making them challenging to process and shape using conventional techniques. In the current study, HfNbTaTiZr ...
