Custom Service
Known industrially as 95% Nickel/5% Aluminum powder (Ni95Al5)-and commonly referred to as aluminum-clad nickel composite thermal spray bond-coat powder-this product is the industry standard equivalent to Metco 450NS and Praxair NI185. It is the most widely used self-exothermic transition bond-coat powder in the thermal spray sector.
The powder is produced via a mechanical cladding process, featuring a nickel core uniformly coated with a thin layer of aluminum. It exhibits a spherical core-shell microstructure, distinguishing it from pre-alloyed nickel-aluminum powders produced by melting.
I. Standard Chemical Composition (Mass Fraction): • Aluminum (Al): 4.0%–5.5% • Nickel (Ni): Balance (94%–95.8%)
Physical and Processing Characteristics
- Excellent flowability ensures smooth powder feeding. It offers high deposition efficiency across plasma, supersonic HVOF, and flame spraying processes, with minimal fume generation, promoting an environmentally friendly production setting.
- Standard particle size specifications: General spray grades include 45–90μm and 30–75μm; a fine powder grade (15–45μm) is available for precision coating of small components.
Key Coating Properties
- Superior Bond Strength: Serving as a transition bond coat, it resolves issues such as poor adhesion and delamination between ceramic or cemented carbide coatings and metal substrates; it is an essential bond-coat material for ceramic thermal barrier coatings and wear-resistant coatings.
-
High-Temperature Oxidation and Corrosion Resistance: Operates stably at temperatures up to 800°C. In high-temperature environments, a dense protective aluminum oxide film forms on the surface, resisting high-temperature oxidation, hot gas corrosion, and water vapor erosion; it also offers resistance to atmospheric and mild acid corrosion.
-
Wear Resistance and Repair Capability: The coating features a dense microstructure with low porosity and moderate wear resistance. It can serve directly as a functional repair layer to restore worn shafts, valves, and pump components that have fallen out of dimensional tolerance. IV. Process Compatibility: Compatible with Atmospheric Plasma Spraying (APS), High-Velocity Oxy-Fuel (HVOF), flame powder spraying, and detonation spraying; universally applicable across these processes without complex parameter adjustments.
Key Application Scenarios
- Aerospace (Primary Application): Bond coats for thermal barrier coatings (TBCs) on aero-engine turbine blades, combustion chambers, and guide vanes; anti-corrosion transition layers for superalloy components, resisting high-temperature gas oxidation and thermal fatigue.
- Power Generation (Gas Turbines): Bond coats for high-temperature gas turbine blades, boiler superheaters, and steam piping; extends the service life of high-temperature components and reduces maintenance frequency.
- Mechanical Component Repair: Dimensional restoration for rolling mill rolls, hydraulic shafts, valve cores, fan impellers, and worn mining equipment parts; restores component tolerances while providing integrated wear and corrosion resistance.
- Metallurgy & Heat Treatment Equipment: Surface protection for high-temperature furnace rolls, heat treatment tooling, and high-temperature fixtures; resists high-temperature oxidation and wear.
- New Energy & General Industry: Spraying of nickel conductive substrates for hydrogen energy equipment; anti-corrosion bond coats for high-temperature piping in marine and chemical industries; intermediate transition layers for various hard, wear-resistant coatings.
Product Advantages Summary
