By adding surface processing to the protective tube and thermowell, various characteristics such as corrosion resistance, abrasion resistance, etc. can be improved.
The special calorizing treatment diffuses and penetrates Fe-Al onto the base metal. In addition, a ceramic layer is formed on Fe-Al layer.
| Structure | Fe-Al is diffused and penetrated over the base metal, and a ceramic layer is further formed in Fe-Al layer. The outermost surface is oxidized to form a stable ceramic coating. |
|---|---|
| Benefits | It has a long life because it has high oxidation resistance, corrosion resistance, and carburization resistance as well as wear resistance. |
| Actual use | Refuse incinerators, industrial waste power plants, coke ovens |
| Calorizing treatment | Special calorizing treatment |
|---|---|
| Oxidation resistance, corrosion resistance, carburization resistance | Oxidation resistance, corrosion resistance, carburization resistance + Abrasion resistance |
