Corrosion and wear-resistant processing of industrial machinery

To improve corrosion and wear resistance, a high-hardness, high-density, high-quality coating is applied to the substrate, enhancing its corrosion and wear resistance.

**Main Corrosion and Wear-Resistant Processing** We have technologies for thermal spraying and welding as the main methods of corrosion and wear-resistant processing. ● Processing by thermal spraying and welding ⇒ Photo 1 **Corrosion and Wear-Resistant Processing by HVOF Thermal Spraying** WC/12Co application A high-hardness wear-resistant coating is obtained. ● Cylinders in powder classification equipment, conveying screws ⇒ Photo 2 **Wire Thermal Spraying Corrosion and Wear-Resistant Processing** SUS316 application Wire thermal spraying on the upper and lower parts of the circulation water pump spindle ● Surface after thermal spraying → Lathe finishing ⇒ Photo 3 **Plasma Thermal Spraying Corrosion and Wear-Resistant Processing** Ceramic application Forms a high-density, high-quality coating. ● Processing of oil seal parts of screw shafts and components of powder classification machines ⇒ Photo 4 **Wear-Resistant Build-Up Welding** ● Wear-resistant build-up welding on the outer circumference of rotors and extruder screws ⇒ Photo 5 Arc, gas, and TIG hard build-up are performed on areas of severe wear. **Comparison of Coating Hardness** ● Hardness comparison table / Hardness test results ⇒ Photo 6 ● Classification of thermal spraying materials by purpose ⇒ Photo 7 **Applications to Products** ● Examples of applications in various industries ⇒ Photo 8, Photo 9 **Introduction of Material Measurement Equipment** ● Also capable of improving corrosion and wear resistance ⇒ Photo 10
