Product Description:

Corrosion resistance:

1. Surface treatment: Surface treatment of pure nickel strips is one of the important methods to improve its corrosion resistance. Common surface treatment methods include electroplating, hot dip plating and chemical plating. These surface treatments can form a protective metal or compound layer to block the contact between the external medium and the pure nickel strip, reducing the occurrence of corrosion.

2. Adding alloying elements: By adding some alloying elements to pure nickel, such as chromium, molybdenum, copper, etc., the corrosion resistance of pure nickel strips can be significantly improved. These alloying elements can form stable oxide films or compounds to prevent the intrusion of corrosive media.

3. Control the purity of components: The purity of components of pure nickel strips also affects its corrosion resistance. By controlling impurity levels in raw materials and production processes, the potential for corrosion can be reduced.

4. Use protective coating: Coating pure nickel strip with a corrosion-resistant protective coating can effectively prevent corrosion from corrosive media. Commonly used protective coatings include organic coatings, inorganic coatings and ceramic coatings.

5. Controlling process conditions: During the processing and use of pure nickel strips, controlling process conditions can also affect its corrosion resistance. For example, parameters such as processing temperature, cooling rate and stress are controlled to reduce internal stress and the possibility of grain boundary corrosion.

Influencing factors:

1. Temperature: Temperature is one of the important factors affecting the corrosion resistance of pure nickel strips. In high temperature environments, pure nickel strips may suffer from complex corrosion forms such as oxidation, sulfidation, and nitration. High temperature may also accelerate the erosion rate of pure nickel strips by corrosive media. Therefore, the corrosion resistance of pure nickel strips may decrease in high temperature environments.

2. Humidity: Humidity is another factor that affects the corrosion resistance of pure nickel strips. In a high-humidity environment, pure nickel strips are easily in contact with moisture, creating conditions for electrochemical corrosion. Oxygen, chlorine and other substances in moisture can accelerate the corrosion rate of pure nickel strips. Therefore, high humidity environments may have a negative impact on the corrosion resistance of pure nickel strips.

3. Corrosive media: Different corrosive media have different effects on the corrosion performance of pure nickel strips. For example, corrosive media such as strong acid, strong alkali, and salt water may cause serious corrosion to pure nickel strips. Factors such as the composition, concentration and temperature of specific corrosive media will all affect the corrosion resistance of pure nickel strips.
