What is the use of nickel aluminum alloy wire 95/5 ?
Nickel aluminum alloy wire 95/5 (i.e. alloy wire of 95% nickel and 5% aluminum) is a common spraying material, mainly used in thermal spraying technology.
It has good corrosion resistance and mechanical properties, so it is widely used in the industrial field. The following are the main uses of this alloy wire:
1. Anti-corrosion coating
Nickel aluminum alloy 95/5 is often used for anti-corrosion coating, especially in high temperature and harsh environment. This alloy has good chemical corrosion resistance
and high temperature oxidation resistance, and can provide effective protection for metal surfaces to prevent corrosion and oxidation. Common application areas include:
Chemical equipment: such as anti-corrosion coatings for storage tanks, pipelines and reactors.
Oil and gas industry: used to prevent equipment from corrosion in marine and corrosive environments.
Power plants: especially in boilers, flues and other parts of coal-fired power plants, used to prevent high temperature oxidation and sulfidation.
2. Thermal barrier coating base material
Nickel aluminum alloy 95/5 is often used as the base coating (Bond Coat) of thermal barrier coatings (TBCs). In coating systems,
thermal barrier coatings can protect mechanical parts that work at high temperatures,
such as gas turbine or aircraft engine parts. The base coating of nickel-aluminum alloy can provide good adhesion and high heat resistance.
3. Electrical conductive coating
Due to its good electrical conductivity, nickel-aluminum alloy is also used in electrical conductive coatings. The alloy can be used in areas where conductivity
and corrosion resistance are required,
such as contact surfaces in electronic equipment, surface spraying of electrical connections, etc.
4. Repair and surface regeneration
Nickel-aluminum alloy 95/5 can be used for repair and surface regeneration of mechanical parts. Through thermal spraying technology,
nickel-aluminum alloy can be coated on the surface of worn parts to restore their original size and function. This alloy wire is an ideal choice especially when high strength,
wear resistance and corrosion resistance are required.
Industrial rollers: such as roller repair in the papermaking and textile industries.
Shaft parts: used for dimensional restoration of rotating mechanical parts.
Pumps and valves: Coating nickel-aluminum alloy can extend the service life of these parts.
5. Sealing surface coating
Nickel aluminum alloy wire 95/5 is also used in sealing surface coating,
such as coating on the sealing surface of aircraft engines and turbines. This alloy wire has good self-melting properties
and can form a dense coating to enhance the airtightness and protective performance of the components.
6. High temperature application
The high temperature resistance of nickel aluminum alloy makes it suitable for use in high temperature equipment or high temperature environment,
such as coating of components such as boilers,
heat exchangers, and gas turbines. It can resist high temperature oxidation and corrosion and protect the stability of the substrate under high temperature conditions.
Main advantages:
High temperature and oxidation resistance: maintain good physical and chemical stability in high temperature environment.
Corrosion resistance: resist acid and alkali environment and chemical corrosion, suitable for use in harsh environment.
Good adhesion: when used as a base coating, it can effectively improve the adhesion of the coating.
Strong mechanical properties: with high hardness and wear resistance, suitable for repairing mechanical parts.
In summary, nickel aluminum alloy wire 95/5 is widely used in industrial fields for anti-corrosion coatings, thermal barrier coatings, mechanical repairs, etc.,
especially in high temperature and highly corrosive environments. It can effectively extend the service life of equipment and components and improve their performance.
