Kupferinfiltration

Kupferinfiltration is a term used in metallurgy to describe the process where copper penetrates into the grain boundaries or interstitial spaces of another metal, typically iron or steel. This phenomenon occurs when copper is present in molten form or as a contaminant in contact with a susceptible host metal at elevated temperatures. The copper migrates into the host material, often leading to a significant weakening of the alloy.

The primary concern with Kupferinfiltration is its detrimental effect on the mechanical properties of the affected metal. The ingress of copper can embrittle the host material, making it more prone to cracking and failure under stress. This is particularly problematic in applications involving high temperatures, such as in the manufacturing of steel components or in welding processes where copper alloys might be used as filler materials or be present as contaminants.

Preventing Kupferinfiltration involves careful control of material sourcing and process parameters. Ensuring the absence of copper contaminants in raw materials and avoiding contact with copper-containing substances during high-temperature operations are crucial. In some cases, specific heat treatments or surface treatments can be employed to mitigate the risk or repair damage caused by Kupferinfiltration. The phenomenon is a key consideration in quality control for various metal fabrication industries.
