What are the applications of HVOF nickel-chromium carbide?
HVOF nickel-chromium carbide (NiCr-Cr3C2) coatings are widely used in the following fields due to their high hardness, excellent high-temperature wear resistance and oxidation resistance:
- High-temperature wear protection
Aircraft engine parts: turbine blades, combustion chamber linings, etc., to resist high-temperature airflow scouring and particle erosion.
Gas turbine blades: improve thermal shock resistance and high-temperature oxidation resistance.
- Chemical and energy equipment
Boiler pipelines: prevent high-temperature flue gas corrosion and fly ash wear in coal-fired power plants.
Heat exchanger parts: reduce high-temperature sulfide and chloride corrosion.
Nuclear power valves: enhance radiation resistance and medium corrosion resistance.
- Oil and gas industry
Drilling tools: such as drill pipe joints and valves, to resist wear and corrosion of sand-containing fluids.
Downhole tools: improve durability in high-temperature and high-pressure environments.
- Metallurgy and heavy machinery
Roller surface strengthening: reduce wear and steel sticking during high-temperature rolling.
Blast furnace parts: such as bells and chutes, resist high-temperature material erosion.
- Automobile and rail transportation
Engine exhaust parts: such as turbocharger housings, resistant to high-temperature exhaust gas corrosion.
Braking system components: improve wear resistance and thermal fatigue resistance.
- Other industrial applications
Glass molds: prevent molten glass from adhering and high-temperature oxidation.
3D printing hot end nozzles: reduce wear of high-temperature metal powders.
The coating is particularly suitable for high-temperature wear, corrosion or oxidation environments below 800°C, and can significantly extend the life of key components.
