Utilizes plasma to enhance, modify, or enable various manufacturing processes
Involves the use of ionized gas (plasma) to interact with materials
Achieves high temperatures and reactive environments
Provides precise control over process parameters
Modifies surface properties and enables unique material synthesis
Components of plasma manufacturing systems
Plasma source generates and sustains the plasma discharge (, , )
Power supply provides electrical energy to the plasma source and controls the power delivered to the plasma
Gas delivery system supplies the working gas (, , ) to the plasma source and regulates gas flow rate and composition
or reactor contains the plasma and the workpiece and maintains the desired pressure and atmosphere
removes excess heat from the plasma source and other components and ensures stable operation and prevents overheating
Applications and Types of Plasma in Manufacturing
Role of plasma in manufacturing
removes contaminants and improves adhesion
creates reactive surface groups for enhanced bonding
selectively removes material for patterning or texturing
Thin film deposition
() deposits thin films using plasma-activated precursors
uses plasma to eject atoms from a target material and deposit them on a substrate
Material synthesis
uses to melt and deposit materials, forming coatings or freestanding parts
employs plasma to enhance the sintering process, reducing processing time and temperature
and welding
uses a high-velocity plasma jet to melt and remove material, enabling precise cutting of metals (stainless steel, aluminum)
utilizes plasma to generate high heat and fuse materials together (titanium, nickel alloys)
Thermal vs non-thermal plasmas
Thermal plasmas
High temperature (≥ 10,000 K) and high electron density
Electrons, ions, and neutral species are in thermal equilibrium
Examples: DC plasma torches, plasma spray, plasma cutting, and welding
Non-thermal plasmas
Low gas temperature (< 1,000 K) and high electron temperature
Electrons are highly energetic, while ions and neutrals remain relatively cold
Examples: RF and microwave plasmas, dielectric barrier discharges, corona discharges
Used in surface modification, thin film deposition, and material synthesis processes (plasma polymerization, plasma-assisted atomic layer deposition)
