SYNCO Cr?C??NiCr Thermal Spray Powders
High-Temperature Wear, Erosion & Oxidation Protection
SYNCO Cr?C??NiCr (Chromium Carbide?Nickel Chromium) thermal spray powders?are premium-grade carbide powders developed for?HVOF, HVAF, and plasma spray applications?where components operate at?high temperatures with severe wear, erosion, and oxidation.
Unlike WC-based coatings,?Cr?C??NiCr retains hardness and coating integrity at elevated temperatures, making it the preferred choice for hot service environments.
Why Cr?C??NiCr?
- Excellent?wear and erosion resistance at high temperatures
- Superior?oxidation and hot corrosion resistance
- Better?thermal stability?than WC?Co at elevated temperatures
- Strong adhesion and dense coatings with HVOF/HVAF
Standard Chemical Compositions (wt.%)
