Characterization and Boron Diffusion Kinetics on the Surface-Hardened Layers of Royalloy Steel
Coatings, 2023 The Royalloy steel was boronized at 1173, 1223, 1248, 1273 or 1323 K for 1, 3, 5, 7 or 10 h using a Durborid powder mixture. The boronized samples were analyzed by scanning electron microscopy, X-ray diffraction and Vickers microhardness testing.

Development of accuracy enhancement system for boron meters using multisensitive detector for reactor safety [PDF]
, 2020 Boric acid is used as a coolant for pressurized-water reactors, and the degree of burnup is controlled by the concentration of boric acid. Therefore, accurate measurement of the concentration of boric acid is an important factor in reactor safety.

Izvestiya of Altai State University, 2020 As is known, boriding is carried out to increase the wear resistance and corrosion resistance of iron-carbon alloys. Along with high hardness, borides, unfortunately, have very high fragility and high refractoriness. An effective way to counter the fragility of boride layers is to form a composite structure consisting of inclusions of solid borides in ...

Boriding of steel surface with beams of boron atoms
MATEC Web of Conferences, 2018 We consider a new method for hardening the steel surface, which differs from the known CHT boriding method in the possibility of creating a surface with a lower fragility.
