What Is Thermal Spraying

---

Thermal spraying technology is one of the most effective surface modification techniques in the field of surface engineering. According to GB/T 18719-2002 “Thermal Spraying Terminology and Classification,” the definition of thermal spraying is: the method in which the spraying material is heated to a plastic or softened state inside or outside the spray gun, then sprayed onto the pre-treated surface of the substrate, essentially maintaining its unmelted state to form a coating. Thermal spraying imparts special functions to the substrate surface.

With the development of related technologies, various thermal spraying techniques have emerged. Modern thermal spraying technology has expanded beyond just the “thermal” aspect. The formation of coatings now includes not only solid-phase deposition but also gas-phase deposition or deposition involving all three phases: solid, liquid, and gas.

Recently developed cold gas dynamic spraying technology involves completely solid-phase deposition; PS-PVD (Plasma Spray Physical Vapor Deposition), LPPS (Low Pressure Plasma Spray) ultra-low pressure plasma spraying technology can achieve gas-phase deposition or solid, liquid, and gas-phase deposition. These technologies complement and expand the scope of thermal spraying, becoming important components of modern thermal spraying techniques. Thermal spraying technology is a rapidly developing high-tech field, and some coating preparation processes have been incorporated into advanced manufacturing technology lists.

• Customizing thermal spray finishes for specialized applications

Although thermal spray coatings offer versatile solutions for OEMs and manufacturers, certain applications may not be suited for this technology. The geometry of some parts may limit the effectiveness of thermal spray coatings, as optimal application angles are critical for achieving desired results. In cases where extreme heat or high mechanical forces are involved, alternative methods, such as welding, may be more suitable. Furthermore, the deposition of thick coatings can sometimes compromise the structural integrity of the component.

If thermal spray technology is not ideal for your application, cold spray coatings and other surface treatment methods are available to meet your performance requirements. Please consult with one of our surfacing technology experts to identify the most effective solution for your needs.
