TriCom Anti-Corrosion Coating

Introducing TriCom Chrome Coatings

U.S. Chrome is pleased to announce a new line of Green Hard TriCom 801 Replacement coatings specifically developed for elevated temperature dry running applications: TriCom 801 electroplated cobalt chrome carbide (Cr3C2). This new generation of tribological coating provides exceptional wear resistance with low frictional characteristics (up to 800°C). It is non-toxic and environmentally friendly. With a superior hardness and thickness rating, TriCom coatings can run against themselves, against uncoated nickel, iron and cobalt base superalloys, and titanium alloys.

TriCom 801 Anti-Corrosion Coating Durability

Hardness: 300-400 VHN @ 100 gm Load
Carbide Volume Fraction: 12-25% Volume
As-Plated Surface Finish: Ra ≈ 400 µinch (10 µm)
Typical Coating Thickness: .001 - .015" (25-375 µm)

TriCom 801 coating extends the service life of machinery and improves durability. Farm equipment and any machinery subject to high rotational wear are good candidates for TriCom 801 coatings. We anticipate many applications for TriCom 801 and welcome inquiries for its use.
