Fail Safe Tantalum Surfaces for Acid Services
Posted on by dean
Tantalum is an amazing element due to its unrivaled corrosion resistance. As most corrosion resistant alloys have corrosion rates in strong acids, tantalum metal typically has none. Because of this characteristic, tantalum is ideal as a coated diffusion surface and is often used to protect critical stainless steel process equipment from strong acids. However in lethal services, this is not enough, as products need to be fail-safe should there be an unforeseen breach in the tantalum surface and the base steel substrate is exposed.
