Chemical Vapor Deposition Of Tantalum

Chemical vapor deposition of tantalum is a unique tantalum treatment that extends the life of fasteners in a variety of corrosive chemical environments. Stress corrosion cracking (SCC) of fasteners is a common problem where tensile stress and corrosion act simultaneously. Treated with a chemical vapor deposited tantalum layer, corrosion is eliminated and defects caused by stress corrosion are prevented. Tantalum is recognized as the most corrosion-resistant metal for industrial use. The tantalum coating prepared by chemical vapor deposition of tantalum has excellent corrosion resistance and prolongs the service life of various fasteners.

The chemical vapor deposition (CVD) process is used for chemical vapor deposition (CVD) of tantalum coatings, which can produce uniform tantalum layers suitable for complex geometries such as threads. Fasteners treated with CVD tantalum have excellent high temperature corrosion resistance compared to stainless steel. It protects against all forms of corrosion, including stress corrosion, corrosion fatigue, and crevice corrosion in the presence of hot acids, thereby reducing failure. Another advantage is easy disassembly, reducing maintenance time and costs. The metallurgical properties of the tantalum surface combine with a uniform, conformal CVD layer to produce a solid product with economical price and short lead times
