Titanium mesh with excellent corrosion resistance to replace the traditional applicable materials, such as nickel-free stainless steel mesh, aluminum mesh and other metal materials, titanium mesh plate long service life, safe and reliable.
The corrosion resistance of titanium mesh
In the corrosion-resistant medium environment, the surface of the titanium mesh plate generates a dense, strong adhesion, inert oxide film, resulting in passivation phenomenon, protecting the titanium mesh matrix from corrosion, so as to achieve strong corrosion resistance; Especially in the following use of the environment more excellent corrosion resistance, such as: seawater, wet chlorine gas, chlorite and hypochlorite solution, nitric acid, chromate metal chloride and organic salts, etc. (for example: 60% nitric acid, pure titanium wire mesh in nitric acid solution corrosion rate is only 0.001mm.a-1).
Factors affecting corrosion resistance of titanium mesh
- Chemical Composition of the Environment: The types and concentrations of chemicals present in the surrounding medium play a crucial role. Strong acids, alkalis, and certain aggressive ions can potentially affect its corrosion resistance.
For example, highly concentrated sulfuric acid or hydrofluoric acid may have a more significant impact. - Temperature: Elevated temperatures can accelerate chemical reactions and increase the corrosive effect on the titanium mesh.
- Surface Condition: Any damage, scratches, or impurities on the surface of the titanium mesh can compromise its protective oxide layer, reducing its corrosion resistance.
- Oxygen Availability: Sufficient oxygen is necessary for the formation and maintenance of the passive oxide film that provides corrosion protection.
In oxygen-deprived environments, the corrosion resistance might be weakened. - Mechanical Stress: Excessive mechanical stress or deformation can disrupt the structure of the material and the integrity of the oxide layer, making it more susceptible to corrosion.
- Galvanic Coupling: When titanium mesh is in contact with other metals with different electrochemical potentials, galvanic corrosion can occur, affecting its corrosion resistance.
