SYNCO WC?Co?Cr Thermal Spray Powders
High-Performance Tungsten Carbide Coatings for Extreme Wear & Corrosion
SYNCO WC?Co?Cr thermal spray powders?are premium-grade?tungsten carbide?based powders?engineered for?HVOF, HVAF, and plasma spray processes. These powders deliver an exceptional combination of?abrasion resistance, erosion resistance, corrosion protection, and toughness, making them ideal for demanding industrial applications.
Why WC?Co?Cr?
Compared to WC?Co, the?chromium addition?significantly improves?corrosion resistance, oxidation resistance, and coating stability?especially in?wet, saline, acidic, and mildly alkaline environments.
Typical Chemical Compositions (wt.%)
| Grade | WC (%) | Co (%) | Cr (%) | Key Characteristics |
|---|---|---|---|---|
| WC?10Co?4Cr | Balance | ~10 | ~4 | Most common grade; excellent wear + corrosion balance |
| WC?12Co?6Cr | Balance | ~12 | ~6 | Higher toughness; better impact resistance |
| WC?17Co?12Cr | Balance | ~17 | ~12 | Enhanced corrosion resistance for aggressive media |
Note:?Exact compositions can be customized to application needs.
Available Particle Size (Mesh / Micron)
SYNCO supplies WC?Co?Cr powders in tightly controlled size distributions for consistent flowability and deposition efficiency:
- ?45 +15 ?m?(Standard HVOF grade)
- ?38 +11 ?m?(Fine finish coatings)
- ?53 +20 ?m?(Thicker, heavy-duty coatings)
- Custom cuts available on request
Powders are available as?agglomerated & sintered (A&S)?or?crushed & sintered, depending on coating requirements.
Coating Characteristics
- Very high?hardness?(? 900?1200 HV, process dependent)
- Dense coatings with?low porosity
- Excellent?sliding wear, abrasion, and erosion resistance
- Improved?corrosion resistance?vs. WC?Co
