Overview of Thermal Spraying Process

On-site implementation is possible! There is a wide range of options for selecting thermal spray materials, allowing for compatibility with various types of materials.

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
