Spray coating processing SPRAY PROCESSING
Automotive mold spraying with tungsten carbide
Molds—especially hot-work molds—not only operate under high-temperature conditions but also endure wear, compression, impact, and thermal-mechanical fatigue. Consequently, their surface properties are typically subject to stringent requirements. If the surface lacks sufficient hardness, red hardness, oxidation resistance, or corrosion resistance, it is prone to damage during use, thereby shortening the mold’s service life. Therefore, mold surfaces generally undergo surface enhancement treatments. Once a mold surface is scratched, as long as the damage is not severe, it can be repaired, thus extending the mold’s service life. Thermal spraying technology boasts several advantages in surface enhancement and component repair processes: flexible and diverse process methods, a wide range of material choices, convenient and rapid construction, strong adaptability, remarkable repair and enhancement effects, and high economic benefits. This technology is particularly well-suited for large-scale molds and molds operating under severe wear conditions. Among the commonly used techniques for mold surface enhancement and repair are plasma spraying and supersonic spraying. By employing supersonic flame spraying, tungsten carbide coatings can be applied, significantly improving the mold’s surface hardness, wear resistance, and corrosion resistance. The key performance indicators of tungsten carbide coatings are as follows: A. Coating hardness: HV1150 or higher. B. Bonding strength: 68 MPa or higher. C. Porosity: Less than 1%. D. Oxide content: Less than 3%. E. Service environment: Below 250℃, in environments without severe impacts. F. Service life: More than six times that of conventionally heat-treated surfaces.
