High-Quality plasma powder surfacing machine DML-V03CD Supplier, Suppliers

It is a metal surface modification equipment independently developed by our company with completely independent intellectual property rights. The welding process is one of the effective technical methods to improve the wear resistance, corrosion resistance and impact resistance of metal surface.

Product Description

Plasma powder surfacing is a kind of surfacing technology which uses plasma arc as heat source, uses high temperature produced by plasma arc to heat alloy powder and substrate surface rapidly and melt, mix, diffuse and solidify together. After plasma beam leaves, it self excites and cools to form a layer of high-performance alloy layer, so as to realize strengthening and hardening of part surface. The thickness, width and hardness of the surfacing layer can be adjusted freely within a certain range by adjusting the relevant surfacing parameters.

After plasma powder surfacing, a fusion interface is formed between the base material and the surfacing material, which has high bonding strength; the surfacing layer has compact structure, good corrosion resistance and wear resistance; the dilution of the base material and the surfacing material is reduced, and the material characteristics change little; using powder as the surfacing material can improve the selectivity of the alloy design, especially the refractory material can be successfully overlaid, and the wear resistance and wear resistance of the workpiece can be improved High temperature, corrosion resistance.

Key System Enhancements

Welding Machine Power Supply: Many market options use combined argon arc units which are bulky. Our system uses a pure plasma power supply system, achieving a smaller size and lighter weight suitable for any occasion.

Plasma Torch: We utilize a built-in powder feeding system and polyethylene insulation material for the handle. This prevents the powder blockage and electric leakage common in external feeding systems, ensuring user safety and stable production.

Powder Feeder: Moving beyond the common scraper type which causes uneven feeding, our advanced impeller type feeder allows for accurate control of feeding size and speed.

Frequently Asked Questions
What is the primary advantage of plasma powder surfacing?
It uses a high-temperature plasma arc to melt alloy powder and the substrate surface rapidly, forming a high-performance alloy layer with metallurgical bonding and high bonding strength.
What is the typical dilution rate for this technology?
The dilution rate of plasma arc surfacing can be strictly controlled within 5% to 10%, or even less, which minimizes the change in material characteristics.
Can the surfacing layer properties be adjusted?
Yes, the thickness, width, and hardness of the surfacing layer can be adjusted freely within a certain range by modifying relevant surfacing parameters.
Is complicated pretreatment necessary for metal parts?
No, plasma surfacing can be carried out directly on the surface of corroded and greasy metal parts without complicated pretreatment processes.
Why is impeller-type powder feeding better than scraper-type?
The impeller type provides more accurate control over the size and speed of powder feeding, overcoming problems like uneven feeding and powder blocking common in scraper systems.
What kind of bonding is formed between the materials?
The process creates a metallurgical bond between the cladding alloy layer and the workpiece substrate, ensuring the structure is compact and highly resistant to wear and corrosion.
