In the field of electroplating, galvanizing is a common metal anti-corrosion technology. By applying a layer of zinc to the surface of a workpiece, the workpiece can be effectively isolated from direct contact with the external environment, thus preventing corrosion. However, the process of zinc plating itself is accompanied by certain risks, among which hydrogen embrittlement is a problem that cannot be ignored. In this article, we will discuss in depth the need for dehydrogenation of the workpiece after electroplating and mention the role of Bigely galvanizing brightener BZ-518 in this process.
Hydrogen embrittlement, which usually manifests itself as a delayed fracture phenomenon under stress, is due to the fact that during the electroplating process, especially when acid zinc plating is used, electrolysis leads to the decomposition of water molecules and the release of hydrogen ions. These hydrogen ions are reduced to hydrogen gas at the cathode (i.e., the workpiece being plated), where some of the hydrogen escapes in the form of bubbles, but other hydrogen atoms may penetrate into the lattice of the metal.
To reduce the risk of hydrogen embrittlement, plating plants need to dehydrogenate immediately after plating with galvanizing brighteners. Dehydrogenation, also known as dehydrogenation, usually involves heating the plated workpiece in a high-temperature oven, a process that allows penetrating hydrogen atoms to diffuse back into the surface and be released from the metal.
The use of a good galvanizing brightener is also key to reducing hydrogen embrittlement during the plating process. Bigely galvanizing brightener BZ-518 is a product with good performance. It not only improves the gloss and uniformity of the galvanized layer, but also reduces pinholes and pockmarks and even cracks caused by hydrogen embrittlement, ensuring the quality and safety of the galvanized layer.
