We select and implement the optimal processing methods and materials according to various purposes.
- It's troublesome that only this part is worn down. - I want to build up only the worn areas to make them more wear-resistant. - I want to reduce material costs but harden only a specific part. In such cases, thermal spraying is the solution. It is also possible to thermally spray wear-resistant metals, ceramics, or hard materials on just a specific area. It is possible to build up wear-resistant materials on the worn areas as well. First, the base material is mostly irrelevant. Thermal spraying can be done on various materials such as steel (soft steel, stainless steel, anything), non-ferrous metals like aluminum and copper, glass, wood, and more. 【Advantages of Thermal Spraying】 - Depending on the type of thermal spraying, there is almost no thermal distortion (the base material temperature is at most around 200°C). - In addition to wear resistance, different added values can also be provided (corrosion resistance, heat resistance, etc.). - There are abundant thermal spray materials available, allowing for several proposals that are cost-effective.
