Nickel-based alloys are widely used in many industries due to their excellent high temperature resistance, corrosion resistance, high strength and other properties. The following is a detailed introduction:
1. **Aerospace field**:
- **Key component manufacturing**: Nickel-based alloys are the preferred materials for high-pressure and high-temperature components of aerospace vehicles. They can be used to manufacture turbine blades, disks, combustion chambers of aircraft engines, and exhaust systems of aerospace engines. In extreme environments such as high temperature, high pressure, and high speed, nickel-based alloys can maintain high strength and good creep resistance to ensure the safe operation of aircraft. For example, the application of single-crystal nickel-based superalloys in aerospace engines has almost completely eliminated grain boundaries, significantly improving the alloy’s high-temperature resistance, corrosion resistance, and fatigue resistance.
- **Spacecraft structural parts**: Nickel-based alloys are also used in structural parts such as aircraft fuselages and wings. Their high strength can provide sufficient structural support for the spacecraft to ensure stability and safety during flight. sex.
2. **Chemical Industry**:
- **Chemical Equipment Manufacturing**: The production process involves various corrosive media such as strong acids, strong alkalis, and organic solvents. Ordinary materials are difficult to resist for a long time, but nickel-based alloys have excellent corrosion resistance and high temperature stability. It is often used in the manufacture of chemical reactors, heat exchangers, distillation towers and other equipment, which can extend the service life of the equipment and ensure the continuity and safety of production.
- **Environmental protection treatment equipment**: Nickel-based alloys are also used in environmental protection fields such as membrane separation technology and waste gas treatment. For example, it is used to manufacture key components in wastewater treatment equipment, which can resist the corrosion of wastewater and improve the reliability and treatment efficiency of the equipment.
3. **Energy field**:
- **Nuclear Energy**: In nuclear reactors, nickel-based alloys can be used to manufacture key components of nuclear reactors, such as fuel rods, pressure vessels, components in coolant circulation systems, etc. It has good high temperature resistance, radiation resistance, and corrosion resistance, and can work stably for a long time in radioactive environments and high temperature corrosive environments.
- **Thermal Power Generation**: Used to manufacture high-temperature and high-pressure pipes, boiler superheaters, reheaters and other components in thermal power plants. They can withstand the corrosion of high temperature, high pressure and steam, improving power generation efficiency and equipment reliability.
- **New Energy**: With the development of new energy, the application of nickel-based alloys in electric vehicle batteries and other aspects is also increasing year by year to improve the performance and safety of batteries.
