This is an introduction to Kōei Techno System's "Wire Arc Thermal Spraying," which focuses on the repair, regeneration, extension of life, and maintenance of parts, aiming for high-quality parts, wear resistance, heat resistance, and anti-corrosion, similar to preventive medicine, through advanced research and development of machinery. It is a type of representative gas thermal spraying method, where wire-shaped spraying materials are continuously fed into a combustion flame generated by oxygen-acetylene or oxygen-propane, melting them, and forming a film by projecting the atomized molten particles with compressed air. As spraying materials, metals that can be processed into wire shapes range from low melting point materials like zinc and aluminum to carbon steel, stainless steel, and molybdenum. Ceramics and cermet materials, which are difficult to wire shape, are filled into flexible tubes and sprayed. ● Thermal spraying on φ500 rolls ⇒ Photo 1 *For more details, please download the catalog or contact us.

This is an introduction to the "Overview of Thermal Spraying" by Kōei Techno System Co., Ltd., which focuses on the repair, regeneration, extension of life, and maintenance of parts. The company conducts research and development aimed at enhancing the quality of parts, improving wear resistance, heat resistance, and corrosion resistance, similar to preventive medicine, to advance machinery. Thermal spraying is a surface modification technology that involves blowing fine particles of a molten thermal spray material onto a substrate surface to form a coating and enhance surface functionality. 【Classification of Thermal Spraying Methods】 Thermal spraying methods are classified based on the differences in heat sources and spray materials used. ● Classification Table ⇒ Photo 2 【Features of Thermal Spraying】 ■ Wide selection of spray materials, accommodating a variety of materials ■ Faster coating formation speed compared to plating (shorter processing time) ■ Coating thickness can be greater than that of plating or heat-treated coatings ■ Can coat large structures and complex shapes ■ Less thermal impact on the base material compared to welding (reducing deformation and distortion) ■ It is a dry process ■ On-site application is possible ● Basic Process ⇒ Photo 3 【Classification of Thermal Spray Materials by Purpose】 Materials are listed by purpose, including corrosion resistance, heat resistance, and wear resistance, categorized into metals and non-metals. ● Purpose-based Classification Table ⇒ Photo 4
