Product Description:
Pure nickel strip is a strip material made of high-purity nickel metal. Its main component is nickel, usually with a purity of 99% or higher. Pure nickel belt has excellent corrosion resistance and can resist erosion by corrosive media such as acids, alkalis, and salt solutions.
This makes pure nickel strips widely used in the chemical industry for manufacturing chemical storage tanks, pipes, valves and other equipment.
In addition, pure nickel tape also has excellent conductive properties and is one of the important conductive materials in the electronics industry. It has low resistivity and good electrical conductivity, making it suitable for manufacturing circuit boards, connectors, electrodes and conductive components, etc. Pure nickel ribbon also plays an important role in the battery manufacturing and energy fields, where it is used to make lithium-ion batteries, fuel cells, solar cells, etc.
Corrosion resistance:
The corrosion resistance of pure nickel strips in high temperature environments can be improved by coating or covering materials. Coatings or cladding materials can provide an additional layer of protection against corrosion and reduce direct contact with corrosive media, thus extending the service life of pure nickel strips.
The following are some common coatings or cladding materials that can be used to improve the high temperature corrosion resistance of pure nickel strip:
1. Oxide layer: At high temperatures, an oxide layer can form on the surface of pure nickel strips. This oxide layer can provide a certain degree of corrosion protection and prevent further oxidation reactions from occurring. If higher corrosion resistance is required, the quality and thickness of the oxide layer can be improved by controlling oxidation conditions, oxidants, and atmosphere.
2. Metal coating: Applying a layer of corrosion-resistant metal coating, such as nickel-chromium alloy, aluminum, titanium, etc., can improve the corrosion resistance of pure nickel strips. These coatings provide better oxidation and corrosion resistance while maintaining the high-temperature strength of pure nickel.
3. Ceramic coating: Some ceramic materials, such as alumina, zirconia, silicon carbide, etc., have excellent high-temperature corrosion resistance. Coating these ceramic materials provides increased resistance to corrosion and wear.
Coating materials: Applying coating materials such as ceramic fiber, high-temperature glue or ceramic paper to the surface of pure nickel strips can provide certain isolation and protection effects and reduce the contact between corrosive media and pure nickel strips.
Heat treatment process:
Heat treatment can have an impact on the corrosion resistance of pure nickel strips. The specific impact depends on the heat treatment method and conditions used. Here are some common effects:
1. Grain boundary structure and grain size: Heat treatment can change the grain boundary structure and grain size of pure nickel ribbons. Proper heat treatment can lead to the clarity of grain boundaries and refinement of grains, thereby improving the strength and corrosion resistance of the material. Fine grains and clear grain boundaries can reduce erosion by corrosive media and the formation of cracks.
2. Chemical composition uniformity: Solution treatment or aging treatment during heat treatment can improve the chemical composition uniformity of pure nickel strips. Uniform chemical composition can improve the corrosion resistance of materials and avoid local corrosion caused by local composition deviation.
3. Residual Stresses: Heat treatment may introduce or eliminate residual stresses in pure nickel strip. Residual stress may cause increased or decreased susceptibility to stress corrosion cracking, thereby affecting corrosion resistance. Proper control of heat treatment conditions can help reduce residual stress and improve corrosion resistance.
4. Phase Changes and Precipitate Formation: Certain heat treatment conditions may lead to phase changes or the formation of precipitates in pure nickel ribbon. Phase changes and the formation of precipitates can change the crystal structure and chemical composition of the material, thereby affecting its corrosion resistance. Sometimes, the corrosion resistance of pure nickel strips can be improved by properly controlling phase changes and precipitate formation.
