Plasma surface engineering is the high-tech science of using the fourth state of matter to rebuild the outer layer of metal components. Unlike traditional heat treatments that often damage parts with extreme heat, PSE acts as a precise bridge between raw material base and advanced engineering applications.
By applying electrical or electromagnetic fields to gases in a vacuum, the system creates plasma. This ionized gas reacts with the material surface to change its chemical makeup, structure, and shape. Consequently, the metal gains extreme hardness and durability without losing its core strength.
Core Strengthening Mechanisms
Our systems utilize two primary physical effects to ensure your components can handle the toughest industrial environments:
Physical Bombardment Effect
This process works like a nanoscale sandblaster. High-energy ions strike the metal surface at extreme speeds. This action cleans away tiny impurities and oxide layers. More importantly, it creates a microscopic texture that serves as a solid "anchor point" for subsequent coatings. This ensures maximum bonding strength.
Chemical Activation Effect
In this stage, active particles such as Nitrogen or Carbon are injected directly into the metal surface. These particles trigger a chemical reaction that reconstructs the surface components. This creates a brand-new compound layer that is naturally resistant to rust, wear, and friction.
Industrial Equipment & Service Portfolio
We offer a complete range of "Equipment + Service" solutions. Whether you need to purchase a full-scale automated station or require professional metal surface treatment services, our portfolio covers every need.
1. Pulsed Plasma Nitriding (PPN) Systems
These furnaces are the gold standard for hardening precision steel parts.
-
E-MAX Series: Large horizontal systems designed for heavy-duty, oversized workpieces.
-
E-RPNS / E-RPN Series: Bell-type (Chamber) high-frequency pulsed furnaces that ensure absolute uniformity for batch processing.
2. Physical Vapor Deposition (PVD) Equipment
Ideal for creating ultra-hard, thin-film protective shields.
-
E-PAC Series: High-frequency pulsed DC Arc PVD equipment for heavy-load tool coatings.
