The CNC equipment can achieve the high wear and corrosion resistant cladding layer of metallurgical combination over metal parts surface, enhance the wear and corrosion resistance of metal parts, and greatly improve the service life of parts. The equipment is especially suitable for cladding large steel components, featuring stable and reliable operation, strong anti-interference ability, advanced automation, high production efficiency and excellent cladding quality etc., suitable for large-scale promotion.
Features:
1. Reliable arc initiation, precise control of cladding, and powder feeding and breaking function of synchronous arc initiation and arc extinguishing;
2. The control system can automatically cut off the power supply and stop the powder and air supply when the arc is extinguished in the cladding process;
3. Using advanced and reliable numerical control technology, the cladding process is automatically completed after program setting.
4. The plasma torch can be stable and continuous cladding and welding molding operations;
5. High production efficiency, suitable for large-scale industrial production;
6. High heat conversion efficiency and low energy consumption.

Schematic Diagram of Synchronous Injection of Powder and Plasma Beam
● Form annular negative pressure plasma beam, reduce the velocity difference of the powder material in the plasma jet, and reduce the powder loss.
● The pressure equalizing ring groove is around the plasma generator nozzle to obtain flexible plasma beam, reduce scouring force, prevent alloy oxidation, and stabilize arc column.
Basic Principle:
Under the action of high temperature plasma beam, the alloy powder and the workpiece surface are rapidly heated and melted together, mixing, diffusion, reaction, solidification; self-cooling after the plasma beam leaves, the high hardness wear-resisting layer is formed over the surface, so as to realize the surface strengthening and hardening, and enhance the wear resistance of the workpiece. The wear-resisting layer of plasma cladding not only has high hardness, but also will not fall off under impact load, due to metallurgical bonding between the wear-resisting layer and the workpiece matrix.
