The "High-Speed Flame Spraying Process" generates a high-velocity gas flame due to high combustion pressure. Metal and cermet powder materials are fed into this flame, which are then propelled at high speed onto a substrate to form a coating. This process is clean, safe, and capable of forming stable and highly reliable coatings, making it a technology of interest as an alternative to chrome plating in relation to recent environmental issues. 【Features】 - Capable of forming dense coatings - Achieves excellent surface roughness through mirror grinding - Forms coatings with high hardness and excellent wear resistance - Low compositional changes of the sprayed material due to heat and low oxide content within the coating - Produces coatings with strong adhesion to the workpiece *For more details, please refer to the catalog or feel free to contact us.

"Overlay welding process - hardfacing welding" is performed using a gas TIG welder for buildup. Since a deeper diffusion layer is formed between the base material compared to the thermal spraying process, it has excellent interlayer corrosion resistance. *For more details, please refer to the catalog or feel free to contact us.

The "Metarizing Process - Wire Arc" is a method where the material being sprayed is in a wire form and is sprayed using a flame. The wire-shaped material is fed to the nozzle by two feeding rolls. Here, it is continuously melted by an oxygen-acetylene flame and sprayed onto the substrate, which has been refined by a stream of compressed air. The individual refined particles intertwine to create a coating of the desired material. 【Features】 ■ Can spray any metal ■ Can spray onto any substrate ■ Does not cause thermal effects or distortion to the substrate *For more details, please refer to the catalog or feel free to contact us.

In the "Fused Coating Process," after forming a coating through thermal spraying, it is remelted again using a gas torch or electric furnace. This creates an alloy layer between the base material and the coating, achieving metallurgical bonding and resulting in a stronger weld. This coating excels in most mechanical and physical properties. 【Features of Self-Fusing Alloys】 ■ The coating is alloyed. ■ The coating merges with the base material to become integrated. ■ It has wear resistance. ■ It has heat resistance. ■ It has galling resistance. *For more details, please refer to the catalog or feel free to contact us.

The "Locaid Process" is a process primarily used for ceramic coatings, resulting in a denser film. It has an extremely high melting point of 1600 to 2500°C, and exhibits excellent chemical resistance and corrosion resistance. Additionally, it can be sprayed onto any dimensions and shapes. 【Features】 ■ High hardness ■ High wear resistance and low friction rate ■ Minimal thermal expansion ■ Excellent thermal shock resistance and mechanical shock resistance ■ Little deformation of the base material due to heat *For more details, please refer to the catalog or feel free to contact us.

The "Plasma Frame Process" is a method that uses a very high-temperature plasma heat source to coat various high-melting-point materials without causing thermal effects. It can achieve temperatures of up to several tens of thousands of degrees, making it possible to spray most high-melting-point materials. 【Features】 ■ Wear resistance ■ Corrosion resistance ■ Thermal insulation ■ Electrical insulation and conductivity *For more details, please refer to the catalog or feel free to contact us.
