The synergy of chromium and molybdenum on the stable catalysis of Fe-based amorphous alloy powder

Journal of Non-Crystalline Solids, 2021
Abstract The Fe41Co7Cr15Mo14C15B6Y2 amorphous alloy powder was prepared by gas atomization. It was interesting that rhodamine B can be completely degraded within only 6 min by 1 g/L Fe41Co7Cr15Mo14C15B6Y2 and 3 mM H2O2 at pH 5.0 at 313 K. This result can be repeated at least 30 times.

Fe-based amorphous soft-magnetic powder produced by spinning water atomization process (SWAP)

IEEE Transactions on Magnetics, 1999
Fe-based amorphous powder was produced by a new atomization process "Spinning Water Atomization Process (SWAP)", having both high quenching rate and mass production potential. The composition of the alloys was Fe/sub 73/Si/sub 10/B/sub 15/C/sub 2/ and (Fe/sub 0.97/Cr/sub 0.03/)/sub 76/(Si/sub 0.5/B/sub 0.5/)/sub 22/C/sub 2/.

Microstructure and properties of laser clad Fe-based amorphous alloy coatings containing Nb powder

Journal of Non-Crystalline Solids, 2020
Abstract Fe-Cr-Mo-Co-C-B-Nb coatings with the Nb mass fractions of 0, 2, 4 and 6% were prepared on 45 steel by laser cladding. The surface and microstructural evolution, chemical compositions, phases and thermal behavior of the obtained coatings were analyzed using a scanning electron microscope (SEM) equipped with energy disperse spectroscopy (EDS),

Laser joining of plain carbon steel using Fe-based amorphous alloy filler powder

Journal of Materials Processing Technology, 2016
Abstract Laser joining with both longitudinal and transverse joining modes is reported for the plain carbon steel C1010 substrates using Fe48Cr15Mo14Y2C15B6 amorphous alloy filler. The high power (2000–3000 W) laser joining at the laser scanning speed of 6 mm/s resulted in complete fusion and full weld penetration of 3-mm thick steel substrates ...

Study of Novel Fe-Based Amorphous/Nanocrystalline Soft Magnetic Powder Cores with NiCuZnFe2O4 Coating Layer

Journal of Superconductivity and Novel Magnetism, 2021
The FeSiBCuNb amorphous powder prepared by the ball mill crushing was used as the raw material, and the FeSiBCuNb/NiCuZnFe2O4 core–shell structure was prepared by chemical coprecipitation. The soft magnetic powder cores (SMPCs) were then produced from the mixture of the qualified powders with 1 wt% epoxy resin as bonding materials by cold pressing ...

Effects of the Addition of Permalloy Powder on the High-Frequency Magnetic Properties of Fe-Based Amorphous Powder Cores

IEEE Transactions on Magnetics, 2006
FeSiB amorphous powder was produced by gas atomization, and subsequently toroidal-shaped FeSiB amorphous powder cores were prepared by cold pressing, using permalloy powder as an additive. The characteristics of gas-atomized FeSiB amorphous powder and high-frequency magnetic properties of the cores were investigated.

Magnetic properties regulation and loss contribution analysis for Fe-based amorphous powder cores doped with micron-sized FeSi powders

Journal of Magnetism and Magnetic Materials, 2020
Abstract The influences of annealing temperature and mass fraction of gas-atomized FeSi powders within a range of 0 ~ 16 wt% on the soft magnetic properties of Fe-based powder cores, prepared by cold compacting the mixture of the water-atomized FeSiBCCr amorphous powders with diameter of 23 ~ 75 μm and the FeSi powders with size below 13 μm, has been

Magnetic properties of Fe-based amorphous powder cores produced by a hot-pressing method

Journal of Magnetism and Magnetic Materials, 2000
Abstract Fe-based amorphous powder cores with glass binder were fabricated by hot-pressing techniques at 1–1.5 GPa and 683–733 K. The cores had superior magnetic properties compared with Sendust powder cores. The coercivity was half and flux density at 300 O e was 30% higher. The initial permeability up to 1 MHz was about 100 and the loss at 100 kHz

Microstructure and Mechanical Properties of Fe-based Amorphous Composite Coatings Reinforced by Stainless Steel Powders

Journal of Materials Science & Technology, 2015
In this study, a few Fe-based amorphous matrix composite coatings reinforced with various portions (4, 8 and 16 vol.%) of 316L stainless steel powders have been successfully produced through high velocity oxy-fuel (HVOF) spraying.
