In order to meet special requirements such as wear resistance and high temperature resistance, acid and alkali corrosion resistance, high strength and high hardness, it is often necessary to strengthen the surface of tools and parts to make them more suitable for machinery manufacturing, aerospace navigation, transportation energy, petrochemical industry, etc. Harsh working conditions in various industries. And Zhuzhou Century Tool Co., Ltd. has a variety of surface strengthening technologies. Among them, we have rich experience in plasma (PTA) surfacing, supersonic (HVOF) spraying, gas shielded welding, flame cladding, vacuum cladding, solid/salt bath boronizing, thermal diffusion hardening, etc., to provide customers with solutions Solutions for various dilemmas. The following is an introduction to various surface enhancement techniques.
Plasma surfacing: high automation equipment (Castellin), low dilution rate, high bonding strength (metallurgical combination of substrate and hard surface), low heat-affected depth, and wide application range of powder materials.
Gas shielded welding: high efficiency, low cost, high bonding strength (metallurgical combination of substrate and hard surface), impact resistance, and flexible construction.
Flame cladding: high efficiency, high bonding strength (metallurgical combination of substrate and hard surface), low cost, and dense coating.
Vacuum cladding: high efficiency, high bonding strength (metallurgical combination of substrate and hard surface), dense coating, adaptable to special shapes.
Solid/salt bath boronizing: high efficiency, low cost, high hardness, suitable for special shapes.
Composite thermal diffusion: ultra-high hardness, gradient distribution, excellent resistance to heavy-duty strain, and adaptable to irregular shapes.
Supersonic spraying: reliable equipment (Prax JP8000) and process, dense coating, no thermal influence on substrate, excellent bonding strength (mechanical bonding of substrate and hard surface).
