Structure and Specifications
This system features a compact design with a small footprint, making it ideal for use in research institutes, corporate R&D centers, and university laboratories. It utilizes the Arc Evaporation and Condensation Method to produce nanoscale metallic or alloy powders. The internal chamber is a sealed high-vacuum reaction vessel equipped with high-temperature corrosion-resistant electrodes, capable of vaporizing metal feedstock under stable discharge conditions and rapidly condensing it into nanopowders.
The particle size can be precisely controlled through process parameters, typically ranging between 100 nm and 500 nm. The resulting powders have uniform particle size distribution, high purity, and strong reactivity, suitable for experimental research and new material development.
Target Materials and Process Configuration
The system operates based on the principle of arc evaporation, where a high-current arc rapidly vaporizes metal or alloy targets in an inert atmosphere. The metal vapor is then cooled and condensed in the condensation zone to form nanoscale powder particles.
Key features include:
Working principle: High-temperature arc evaporation of metal → Metal vapor condensation → Nanopowder formation.
Powder types: Single-metal powders such as Fe, Ti, Al, Cu, Ni, and selected alloy powders such as Fe-Ni and Ti-Al.
Particle size control: Adjustable by tuning arc power, gas pressure, and cooling rate to achieve precise particle size and distribution.
Powder collection system: Multi-stage cyclone separation and high-efficiency filtration effectively separate particles of different sizes, ensuring high collection efficiency and powder purity.
Optional modules: Real-time particle size monitoring or automatic powder collection systems can be added for continuous production and in-situ process control.
Vacuum and Control System
The system uses a mechanical pump or Roots pump assembly to quickly establish an inert gas atmosphere, typically operating within a pressure range of 100–1000 Pa. Argon or nitrogen can be introduced to prevent oxidation of the powders.
The PLC-based automatic control system enables precise setting and regulation of arc power, discharge duration, gas flow rate, and chamber pressure. The interface provides real-time display of temperature, pressure, power, and condensation zone data. It also supports data recording, process replication, and safety alarms to ensure consistent and reliable experimental operation.
