Surface Hardening Treatment for Automotive Engine Molds
汽车发动机模具
模具耐磨喷涂
Product Description
Surface hardening treatment for automotive engine molds; wear-resistant coating application for automotive molds.
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 typically face stringent requirements. If the surface lacks sufficient hardness, red hardness, oxidation resistance, or corrosion resistance, it is prone to damage during use, 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, thereby extending the mold’s service life. Thermal spraying technology boasts several advantages in surface enhancement and component repair processes: it offers 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 those operating under severe wear conditions. Among the thermal spraying techniques commonly used for mold surface enhancement and repair are plasma spraying and supersonic spraying.
Using the supersonic flame spraying process, a tungsten carbide coating is applied to enhance the mold surface’s hardness, wear resistance, and corrosion resistance.
Main performance indicators of tungsten carbide coatings
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. Operating Environment: Below 250℃, in environments without severe impacts.
F. Service life: More than 6 times that of the heat-treated surface.
