Effect of spatially non-uniform boronization on plasma restart in WEST

Nuclear Materials and Energy
The recent ITER re-baseline with the adoption of a full-W wall calls for mandatory boronization studies. ITER pulses will be inboard limited on the W tiles of the central column for several seconds during the current ramp up phase.

Elimination of inter-discharge helium glow discharge cleaning with lithium evaporation in NSTX

Nuclear Materials and Energy, 2017
Operation in the National Spherical Torus Experiment (NSTX) typically used either periodic boronization and inter-shot helium glow discharge cleaning (HeGDC), or inter-shot lithium evaporation without boronization, and initially with inter-shot HeGDC. To

Deuterium retention behaviors of boronization films at DIII-D divertor surface

Nuclear Materials and Energy
Boron coating of plasma-facing components (PFCs) is widely used in fusion devices to form surface coatings and chemical compounds on the PFCs, thus suppressing plasma contamination by impurities such as oxygen, carbon, and tungsten.

The Hardness of Boride Layer on the S45C Iron (A preliminary study on surface hardening of ferrous material)

Aceh International Journal of Science and Technology, 2012
- The property such as microhardness of boride layer formed on S45C iron was investigated. Boronizing was carried out in a solid medium consisting of nano size powders of 50% B4C as a donor, 45% SiC as a diluent, and 5% KBF4 as an activator treated at ...
