Hydrogen Embrittlement Relief
Hydrogen embrittlement is a condition where hydrogen absorbed into the material during coating processes, especially in high-strength steels, weakens the metal structure and leads to sudden fractures. This risk is particularly critical for safety-sensitive parts after electrolytic plating.
For this reason, post-plating heat treatment (baking) is applied to remove hydrogen from the material, ensuring part safety.
PROCESS
The hydrogen embrittlement relief process is carried out by applying controlled heat treatment at specific temperatures and durations after plating. During this process, hydrogen within the material is removed from the surface through diffusion.
Application parameters are determined according to the material type and customer specifications.
TECHNICAL VALUES
- Process temperature: 180°C – 220°C
- Duration: 2 – 24 hours (depending on the part)
- Application timing: As soon as possible after plating
If hydrogen embrittlement relief is not performed, delayed fractures may occur, especially in high-strength fasteners. This situation poses serious safety risks.
Therefore, it is considered a mandatory process in many industries, particularly in automotive and defense sectors.
Hydrogen embrittlement relief is a critical heat treatment process applied to remove hydrogen absorbed into the material after electrolytic plating. Especially essential for high-strength steel components, this process ensures safe and long-lasting use.
