Tantaline Technology and Products Overview
Tantaline Technology:
All Tantaline® products are tantalum surface alloys, which are created through an innovative tantalum
vapor technology. Through this technology, we are able to create the most corrosion resistant material commercially available today that has the performance of pure tantalum metal without the high cost.
How it works:
Tantaline’s surface alloy treatment has 5 key steps:
1 - A part is selected for treatment. We can use almost any leading OEM part (standard or stainless steel valves, fittings, instrumentation, and thousands of other types).
2 - A furnace is then heated to a temperature between 700 – 900 degrees celsius, whereupon the tantalum metal is chemically reacted and vaporized. The high temperature fosters conditions suitable for solid state diffusion and alloy bonding at an atomic level.
3 - A gaseous atmosphere of tantalum is created and individual tantalum atoms diffuse into the core substrate (typically stainless steel)
4 - The gaseous tantalum begins to metalurgically bond to the substrate, creating the surface alloy. The deposited tantalum layer is securely bonded to the core material by means of a thin alloy zone
5 - The gas phase continues until a dense excess layer of pure tantalum metal is grown onto the surface. The final tantalum surface is approximately surface 50 microns thick (0.002”) with all the characteristics and chemical properties of pure tantalum (Ta) metal.
The result:
The completed part is an entirely new product that maintains the original OEM part’s size and shape but that now has the same chemical properties and corrosion resistance as a pure tantalum part. It is also extremely rugged and durable, with the ability to handle an extremely high degree of stress caused by mechanical load, vibrations, rough physical handling, or temperature variations during use.

 Tantaline Products
The Tantaline vapor technology can be applied to almost any commercially available part (standard/ stainless steel or other). Below is a sample list of parts that are available through Tantaline. Since the process is geometrically independent, most any part (even highly complex ones on both internal and external surfaces) can be custom treated.

Quality Guarantee
All Tantaline parts are inspected for the integrity of the surface by placing the parts in boiling 32% HCl acid for 48 hours (which only pure tantalum metal can survive in). The products are 100% guaranteed to be free from any defects and have the chemical properties of commercially pure tantalum.
