Corrosion and wear-resistant processing by HVOF thermal spraying (High Velocity Oxy-Fuel spraying)

It is suitable for thermal spraying of cermets such as WC-Co and WC-CrNi, resulting in a high-hardness wear-resistant coating.

This is an introduction to Kōei Techno System's "Corrosion and Wear Resistant Processing by HVOF Coating (High Velocity Oxygen Fuel Coating)," which focuses on the repair, regeneration, extension of life, and maintenance of parts. We conduct research and development aimed at enhancing the quality of parts, improving wear resistance, heat resistance, and anti-corrosion, similar to preventive medicine, to advance machinery. HVOF is a type of gas thermal spraying method that utilizes a super high-speed jet stream generated by the combustion of high-pressure oxygen. Because the material collides with the substrate at high speed, it forms a coating with very high adhesion and density, resulting in a high-quality film. It is suitable for spraying cermets such as WC-Co, yielding high-hardness wear-resistant coatings. 【Screws】 ● Supply machine screw ⇒ Photo 1 ● Conveying screw ⇒ Photo 2 【Crushing Equipment】 ● Inner wall of the crushing equipment ⇒ Photo 3 ● Wall surface of the crushing equipment ⇒ Photo 4 ● Processed inner wall of the crushing equipment ⇒ Photo 5 【Pump Parts】 ● Pump parts ⇒ Photo 6, Photo 7 ● After processing pump parts ⇒ Photo 8 【Powder Classification Equipment】 ● Inner cylinder of the powder classification equipment ⇒ Photo 9 *For more details, please download the catalog or contact us.
