93/7 CrC-NiCr


Purtech 93/7 nickel chromium-chromium carbide coating provides excellent resistance to wear by hard surfaces and fretting at elevated temperatures to 1500 degrees F. The resultant HVOF applied coating is moderately hard and well bonded.

As in the case of all of our HVOF carbide coatings, the 93/7 nickel chromium-chromium carbide coating exhibits negligible porosity.

The information provided is believed to be accurate, however actual coating properties may vary due to part geometry, preparation method, and other application and part constraints. No warrantee is expressed or implied.
