Hkezeléssel

Hkezeléssel is a Hungarian-language compound used in technical contexts to denote processing or treatment performed with hydrogen or designated by the letter H. It is typically written as H-kezeléssel or with a hyphen, and occurs in phrases describing a processing step applied to a material or component.

Etymology and scope: Based on the noun kezelés (treatment, handling) with the leading element H- representing hydrogen (hidrogén) or a placeholder for a specific H-process in a given workflow. The construction functions as a descriptive modifier naming the treatment rather than a distinct technical method in itself.

Applications and methods: In materials science and metallurgy, H-kezeléssel refers to hydrogen-related processing such as hydrogenation, hydrogen annealing, degassing, or surface modification with hydrogen-containing atmospheres. It may be performed in gas furnaces, vacuum systems with hydrogen, or plasma-assisted setups. The exact conditions (temperature, pressure, duration) depend on the material and the intended property change (softening, grain growth, defect passivation, or corrosion resistance).

Considerations: Hydrogen-containing treatments require appropriate safety measures due to flammability and embrittlement risks, particularly for high-strength steels and certain alloys. The effects on microstructure are often subtle and require characterization to confirm desirable outcomes.
