Stellite cobalt-based alloy impellers are impeller components manufactured using Stellite cobalt-based alloys. They possess excellent high-temperature resistance, wear resistance, and corrosion resistance, and are widely used in extreme operating conditions such as aerospace, energy, chemical, and oil and gas industries.
Material Properties:
Stellite cobalt-based alloys use cobalt as a matrix, with the addition of elements such as chromium, tungsten, and carbon. The resulting hard carbide phase allows it to maintain high strength and structural stability in high-temperature (above 1000℃), high-pressure, and corrosive environments, while also exhibiting excellent resistance to abrasive wear, erosion, and adhesive wear.
Applications:
Aerospace: Used in impeller assemblies for jet engines and turbochargers, ensuring reliable operation in high-speed, high-temperature environments and guaranteeing power output.
Energy Industry:
Used as a key impeller component in gas turbines and steam turbines to achieve efficient energy conversion; also used in pump impellers in oil extraction equipment to resist wear and corrosion in harsh downhole environments.
Chemical and Marine Engineering:
Impellers suitable for chemical reactors and seawater desalination equipment, capable of withstanding corrosion from acidic and alkaline media and seawater, ensuring long-term stable operation.
Manufacturing Process:
Typically employs precision casting (such as lost-wax casting), powder metallurgy, or additive manufacturing (3D printing) to ensure the accuracy and performance consistency of complex impeller structures. Some impellers also undergo surface polishing and laser cladding to further enhance wear resistance and sealing performance.
