Hydrogen embrittlement is a process in which metals, particularly high-strength steels, become brittle and fracture due to the absorption and diffusion of hydrogen atoms into their structure. This phenomenon often occurs during manufacturing processes such as electroplating, welding, or pickling, where hydrogen is introduced to the metal surface. The absorbed hydrogen weakens the metal's internal bonds, making it susceptible to cracking or sudden failure, even under normal loads. Preventing hydrogen embrittlement involves controlling exposure to hydrogen, using proper materials, and applying post-process treatments like baking to remove absorbed hydrogen.
