Tantalum Coating

Tantalum Coating involves applying a thin, high-purity layer of Tantalum metal onto a substrate material, typically a less-expensive steel. The purpose is to transfer Tantalum's renowned property—its near-total immunity to chemical corrosion—to the surface of a critical component. Tantalum is highly resistant to virtually all acids, including concentrated hydrochloric and nitric acids, and maintains this resistance at high temperatures. These coatings are primarily applied using methods like chemical vapor deposition (CVD) or physical vapor deposition (PVD). Tantalum Coatings are essential for protecting heat exchangers, reactor vessels, dip tubes, and mixing components in the highly aggressive environments of the chemical and pharmaceutical industries. Zeron Fastners supplies components with Tantalum Coatings for optimal corrosion protection.
