Titanium wire mesh is difficult to be corroded due to its special metallographic arrangement and surface passivation film, making it difficult to chemically react with the medium under normal conditions, but it is not impossible to be corroded under any conditions. Titanium wire processing is in the presence of corrosive media and inducements (such as scratches, splashes, cutting slag, etc.). Titanium mesh can also be corroded by slow chemical and electrochemical reactions with corrosive media.
And under certain conditions, the corrosion rate is appropriately fast and rust phenomenon occurs, especially pitting corrosion and crevice corrosion. Therefore, during the processing operation of the titanium wire mesh, all useful methods should be adopted to prevent the corrosion conditions and inducements. happened. In fact, many rust conditions and inducements (such as scratches, splashes, cutting slag, etc.) also have obvious adverse effects on the appearance quality of titanium wire mesh, and should and must be overcome.
How to deal with the appearance of titanium wire mesh? Commonly used titanium wire mesh surface treatment skills have the following treatment methods: Titanium wire mesh surface natural whitening treatment: during the processing of titanium mesh, black oxidation occurs through coiling, binding, welding, or artificial surface fire heating. Skin. However, this method is expensive, pollutes the environment, harmful to the human body, and highly corrosive, and is gradually being screened.
Titanium wire mesh surface mirror bright treatment method: according to the messiness of titanium mesh products and user requirements, mechanical polishing, chemical polishing, electrochemical polishing and other methods can be selected to achieve the mirror luster. Gr5 Ti-6Al-4V Titanium Wire surface color treatment: titanium mesh The color not only imparts various colors to the titanium mesh products, but also adds the variety of colors to the products, and improves the wear resistance and corrosion resistance of the products.
