Typical Physical & Spray Properties

Density: 8.83 g cm⁻³
Elongation: 40 %
Max. service temperature: 1 300 °C (short-term 1 390 °C)
As-sprayed hardness: 200-260 HV
Bond strength on mild steel: ≥ 55 MPa
Oxide content after spraying: ≤ 3 %
Surface finish: bright, smooth, free of draw-marks

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
