Web1 feb. 2011 · The resulting HVOF coating has a hardness of 1,200 to 1,500 HV compared to 800 to 1,000 HV for hard chrome. This makes it highly wear-resistant, but more difficult to grind and otherwise finish. Courtesy of United Grinding. A tungsten-carbide HVOF-coated turbine shaft before (top) and after grinding.

HVAF & HVOF Tungsten Carbide Coating: How to Spray the Best

WebCT2302-2 a Prealloyed Chrome Carbide Nickel Chromium applied using the HVOF process. ... 75% Chromium Carbide, 25% Nickel Chromium. Bond Strength: 10,000 psi. Coating Porosity: Less than 2%. Coating Hardness: DPH300 800-950. As-sprayed Surface Roughness: 200 Ra. For the Following Applications: WebGeneral Description: This Chromium Carbide HVOF is the “work horse” coating of MOGAS and is used as standard for severe service unless conditions dictate otherwise. Hardness is derived from the Chromium Carbide particles contained in the Ni ckel-Chromium binder. Hardness is generally maintained at elevated temperature. WebHVOF Chromium Carbide coatings are dense (less than 1/2 volume percent porosity) and well bonded (tensile bond strength in excess of 12,000 psi, 83 MPa). These coatings, however, may be best characterized by their high macro and microhardness which translates into excellent high temperature wear resistance.
