Carbide Coatings
• Wear resistant hard facing materials
• Typical thickness of 0.1 to 0.5mm
• Extremely hard coating materials 65-72 RC (900-1300Hv)
• Very dense >99%
• Smooth coatings of typically 3 to 4 Microns Ra as sprayed finish
• Outstanding adhesion with HVOF-applied coatings generally >10,000 psi bond strength
• Applied by HVOF and HP/HVOF
• Hard Chrome plating replacement
• Can be ground to a 0.4 Microns Ra surface finish, or super finished to 0.1 Micron Ra
Common Coatings:
• Tungsten Carbide : WC/Co, Wc/Ni, Wc/Co/Cr, Wc-CrC-Ni erc
• Chrome Carbide : Cr3C2, Cr3C2/NiCr
• Titanium carbide
