Tungsten Carbide Surface Strengthening Technology

In order to meet the special requirements of wear resistance, high temperature resistance, acid and alkali corrosion resistance, high strength, high hardness, etc., it is often indispensable to strengthen the surface of the tools and components to make them more suitable for the harsh working conditions in various industries such as machinery manufacturing, aerospace and navigation, transportation and energy, petrochemical and other fields. Typical of which are: plasma (PTA) surfacing, supersonic (HVOF) spray, gas shielded welding, flame cladding, vacuum cladding, solid / salt bath boron penetration, heat diffusion hardening, etc., the following isall kindsof surface strengthening technology related to the introduction:

A. Plasma cladding: Highly automated equipment , low dilution rate, high bonding strength (metallurgical bonding between substrate and hard surface), low heat-affected depth, wide range of powder materials.

B. Gas Shielded Welding: High efficiency, low cost, high bonding strength (substrate to hardfacing), impact resistance, flexible construction.

C. Flame cladding: high efficiency, high bonding strength (metallurgical bonding between substrate and hard surface), low cost, dense coating.

D. Vacuum cladding: high efficiency, high bonding strength (metallurgical bonding between substrate and hard surface), dense coating, adaptable to special shapes.

E. Solid/salt bath boriding: high efficiency, low cost, high hardness, adaptable to special shapes.

F. Composite thermal diffusion: ultra-high hardness, gradient distribution, excellent resistance to heavy-duty strains, adaptable to special shapes.

G. Supersonic spraying: reliable equipment (Plexus JP8000) and process, dense coating, no thermal influence on the substrate, excellent bonding strength (mechanical bonding between substrate and hard surface).
