Hydrogen embrittlement is a process in which hydride-forming metals such as titanium, vanadium, zirconium, tantalum, and niobium become brittle and fracture due to the introduction and subsequent diffusion of hydrogen into the metal1. Practically all metal materials can be damaged by the absorption of hydrogen, if a sufficient quantity can penetrate into the material2. Preventing the occurrence of hydrogen embrittlement requires understanding the source of hydrogen, the process of hydrogen absorption and transportation in metals, the embrittlement mechanism and the visual appearance.

Alfa Chemistry provides hydrogen embrittlement failure testing and other failure analysis to help you detect possible hydrogen exposures during manufacturing, evaluate hydrogen embrittlement, and better understand the cause of product failure. We have experienced experts in various industries, who can communicate with you to determine the root cause of the failure, provide relevant solutions and suggestions, and reduce the recurrence of the same failure. At the same time, we are able to provide failure analysis services for a variety of retail products, including Personal Care & Beauty Products, Healthcare, Chemicals, Household and Apparel, Stationery and Office Supplies and Toys & Children Products. If you have any questions about failure analysis, please feel free to contact us.
Alfa Chemistry specializes in various materials industries:
