What are some of the process requirements for surface spraying technology?

1- For requirements and methods of common surface pretreatment processes, refer to http://www.corrosion.com/prep.asp; it is in English. Generally, paint manufacturers have their own requirements. The selection of sand material must take into account the coating’s requirements regarding surface roughness. 2- The commonly used method for spraying nowadays is airless spraying. 3- Different coatings have varying spraying requirements, such as the interval between layers and the dry film thickness. 4- Depending on the application area and required level of protection, appropriate coatings should be selected; for tanks, this usually involves an epoxy (zinc-rich) primer, a high-solid epoxy coat, followed by a polyurethane topcoat. They vary. I’m not sure if this is relevant to your question – are you in the coating processing industry? Is it construction again?

1. Laser heat treatment technology: Laser heat treatment is a high-tech process for rapid local surface quenching, which is primarily used to strengthen the surface of components. It can increase the surface hardness, wear resistance, strength, and high-temperature resistance of metal materials and parts, while allowing the core of the parts to retain good toughness. As a result, the mechanical properties of these parts feature excellent wear resistance, high impact toughness, and high fatigue strength. The use of laser heat treatment technology can significantly improve product quality and double the service life of products. Laser heat treatment has significant advantages over traditional quenching processes: the surface hardened layer has a fine and uniform structure, is not constrained by the shape of the part, can achieve a hardness of up to HRC60, and its thickness can reach up to 4 MM. 2. Laser cladding technology: A laser-based process that deposits a layer of material with specific physical properties on the surface of a designated workpiece, in order to improve its surface properties or restore the original geometric dimensions of the part. High-performance optional materials are used to modify the substrate surface, resulting in a cladding structure that is fine-grained, free of microdefects, and features high metallurgical bonding strength. Laser cladding technology can also be used to repair holes and cracks on the surface of materials, restoring the geometric dimensions, morphology, and properties of damaged workpieces. 3. The application of laser processing technology imposes no restrictions on the geometric dimensions of mechanical parts’ shapes; laser processing can be carried out wherever the laser can reach ； There are no restrictions on the base material; steel, iron, non-ferrous metals, and certain types of cemented carbides can all be repaired ； The metal surface can be modified to enhance the physical properties of parts such as wear resistance, corrosion resistance, and high-temperature resistance, thereby extending the service life of these parts and reducing production costs.
