DOUBLE PROTECTION FOR HIGHLY-CORROSIVE APPLICATIONS

Bi-Protec® is a two-step process that combines Electroless Nickel with an overlay of Armoloy TDC®. Excellent for highly corrosive applications, this dual coating involves an initial layer of electroless nickel at a thickness of .0002/.003″ followed by a .0001/.0005″ deposit of thin dense chrome.

In addition to maximum corrosion protection, Bi-Protec® also provides the benefits of Armoloy TDC® to aluminum components by virtue of the electroless nickel under-layer, which adheres absolutely to the aluminum substrate.

Popular for extreme situations like downhole applications in the Oil and Gas sector, Bi-Protec® offers the best combination of wear and corrosion resistance that Armoloy has to offer.
