Q&A【2】

Q&A about thermal spraying processing and ceramic laser engraving processing.

●What functions does the thermal spray coating have? Wear resistance, corrosion resistance, heat resistance, thermal insulation, thermal barrier properties, high-temperature oxidation resistance, electrical insulation, electrical resistance, conductivity, electron emission, magnetic shielding effect, far-infrared radiation, lightweighting, resistance to molten metal, decoration, rigidity enhancement, braking distance reduction, release properties, gap filling, non-giving effect, sensor film, anti-slip, wear part recovery, superconducting film, static electricity prevention, antibacterial effect. ●What is the maximum size that can be processed by thermal spraying? The largest size in the past was Φ1,600×8000L; roll grinding machine capacity Φ1500×8,000L. ●What is the difference from welding build-up? In welding, there are restrictions on the material properties. It is said that there is a dilution rate of about 30%, and to achieve the catalog hardness, it is necessary to apply three layers, which also leads to distortion of the material. Thermal spraying can keep the material temperature below 100°C, preventing distortion, allowing for processing of both new and repaired items without distortion. ●How does thermal spraying adhere? Basically, there are no issues in areas that rotate or slide, but in areas with impacts, it can cause peeling.
