Schutzgasatmung

Schutzgasatmung is a technique used in electroplating and other industrial processes to prevent gases from entering the workpiece or the electrolyte solution. The term "Schutzgasatmung" is German for "protective gas atmosphere" or "gas shielded atmosphere".

In electroplating, Schutzgasatmung is employed to prevent the attachment of hydrogen bubbles to the workpiece, which can cause defects in the plated layer. When a workpiece is submerged in an electrolyte solution, hydrogen gas can form on its surface due to the electrochemical reaction. The rapid release of these bubbles can cause damage to the workpiece and the surrounding equipment.

To prevent this problem, a gas is introduced into the electrolyte solution to suppress the release of hydrogen gas. This gas is typically a noble gas, such as argon or helium, and it surrounds the workpiece, creating a barrier of inert molecules that do not react with the electrolyte. The Schutzgasatmung technique is able to minimize defects and improve the quality of the electroplated layer.

Schutzgasatmung is also used in other industrial processes, such as metalworking and welding, where it serves to protect the molten metal from atmospheric gases that can cause porosity and other defects. Overall, this technique has become an essential tool in various manufacturing processes where the control of gas atmosphere has a significant impact on product quality.
