Key Coating Characteristics
✔ Ultra-dense microstructure, porosity < 2 %
✔ Self-bonding to most iron & nickel-base substrates (no intermediate layer required)
✔ Forms in-situ Al₂O₃ scale → excellent high-temperature oxidation & corrosion resistance
✔ Outstanding thermal-shock & scuff resistance

Recommended Spray Parameters (Arc-Spray)
Voltage: 30-34 V | Current: 120-180 A | Air pressure: 0.55-0.65 MPa
Stand-off distance: 150-200 mm | Traverse speed: 200-400 mm s⁻¹

Main Applications

Bond coat for ceramic top-coats (ZrO₂, Al₂O₃, Cr₂O₃) on gas-turbine blades, piston rods, boiler tubes
Corrosion-resistant under-layer for chemical pump shafts, fan impellers, marine propellers
Restoration of worn glass-moulds, forging dies, paper dryer rolls
EMI shielding & conductive coatings in electronic housings
