|---|---|---|---|---|
| Process Focus | Dense carbide and alloy coatings | Ceramic, oxide and thermal barrier coatings | Metallic wire coatings and repair buildup | Dense wear-resistant and ceramic coatings |
| Typical Feedstock | Powder | Powder | Conductive metal wires | Powder |
| Best Used For | Wear, corrosion, erosion and critical industrial parts | Ceramics, insulation, heat protection and functional coatings | Corrosion protection, large parts, metallic buildup and repair | Precision wear parts and dense coating applications |
| Typical Materials | WC-Co-Cr, WC-Co, Cr3C2-NiCr, Ni alloys | Al2O3, Cr2O3, ZrO2, YSZ, NiCrAlY, Mo | Zinc, aluminum, Zn-Al, stainless steel, bronze, NiAl, cored wire | Carbide, alumina, dense ceramic coatings |
