The performance of cut-resistant tungsten wire in a strong alkali environment is complex. Although tungsten wire exhibits good corrosion resistance in most environments, its corrosion resistance will be affected to a certain extent under strong alkali conditions.
First, strong alkaline substances contain a large number of hydroxide ions (OH-), which can react with the oxide layer (such as tungsten oxide WO3) that may exist on the surface of the tungsten wire to form soluble tungstates (such as H2WO4) and release hydrogen. This reaction is reversible, and when the concentration of hydroxide ions in the alkaline substance is higher, the corrosion rate of the tungsten wire will also be accelerated accordingly. Therefore, in a strong alkaline environment, the cut-resistant tungsten wire may be corroded to a certain extent.
However, it is worth noting that the corrosion resistance of the tungsten wire itself is relatively strong, especially in the absence of the synergistic effect of other external factors (such as high temperature, redox environment, etc.). In addition, in order to protect the stability of the tungsten wire in a specific environment, some measures can be taken to slow down or prevent the occurrence of corrosion. For example, carbonate substances (such as potassium carbonate K2CO3, sodium carbonate Na2CO3, etc.) can be added to a strong alkaline environment. These substances will react with hydroxide ions to generate carbon dioxide and precipitate soluble carbonates, thereby forming a protective film on the surface of the tungsten wire to slow down and inhibit the corrosion rate.
In practical applications, appropriate materials and protective measures should be selected according to the specific working environment and requirements to ensure the normal operation of the equipment and extend its service life.
