Corrosive wear of multi-layer Fe-based coatings laser cladded from amorphous powders [PDF]

Wear, 2019
Abstract Since amorphous alloys exhibit good wear and corrosion resistance, they are supposed to be applied as a candidate implant material. In this work, using laser cladding, Multi-layer Fe-based alloy coatings were fabricated from amorphous powders on 316L stainless steel (SS) substrate.

A mutli-technique search for the most primitive CO chondrites [PDF]

, 2018
As part of a study to identify the most primitive COs and to look for weakly altered CMs amongst the COs, we have conducted a multi-technique study of 16 Antarctic meteorites that had been classified as primitive COs. For this study, we have determined: (

Influence of alloying (Cr, Fe, Ni) on the corrosion resistance of layers formed by electron-beam processing

Chimica Techno Acta, 2022
The paper presents the results of comparative analysis of the properties of coatings based on chromium, nickel and iron borides. The alloy obtained in the process of electron-beam surfacing of the powder mixture “amorphous boron – 10 wt.% chromium” has ...

Ultrafast reductive dechlorination of carbon tetrachloride by amorphous Fe78Si9B13 alloy

Results in Physics, 2019
Amorphous Fe78Si9B13 ribbons and zero-valent iron (ZVI) powder were used to remove carbon tetrachloride (CTC) in the neutral oxic environment. The amorphous Fe78Si9B13 ribbons showed significantly better dechlorination performance than the ZVI powder ...

Shock consolidation of Fe-based amorphous alloy powder.

Journal of the Japan Society of Powder and Powder Metallurgy, 1988
Dynamic compaction of Fe-based amorphous alloy powder was performed by using a gun-type momentum trap method. Residual shock effects on the amorphous alloy samples was characterized by microstructural analysis (i.e. optical, SEM, and TEM observations), X-ray diffraction analysis, tensile strength test, and measurement of it's soft magnetic properties ...
