In the manufacturing or medical device industry, plasma technology forms an intricate and vital component. Its applications are not limited to these sectors alone. In fact, the exploration of plasma potential is continuously evolving, promising a brighter and technologically advanced future.
Plasma, the fourth state of matter, serves as a significant resource with versatile applications in the realm of engineering. Derived from heating a gas to high temperatures, plasma, an ionised gas with ions and electrons, is known for its electrical conductivity and generated magnetic fields. For such reasons, plasma is heavily utilised, innovating engineering practices and applications.
Plasma has revolutionised the broad arena of engineering, with diverse applications ranging from manufacturing to the communication sector. Its ability to interact with electromagnetic radiation, owing to the high concentration of charged particles, facilitates these applications.
Plasma Etching: In the field of microelectronics manufacturing, plasma etching is a crucial method. It is an industrial process where material is removed from a surface to create miniature circuits. The high-energy particles of the plasma etch away the material, making extremely precise cuts, a process that is essential in chip fabrication.
Plasma Spraying: A valuable plasma use in the materials engineering realm is plasma spraying. This method coats a material with a layer of thermal spray coating material at high temperature, driven by the ionised gas of the plasma. This process enhances characteristics such as resistance to heat, erosion, or corrosion and is used extensively in fields like aviation and turbine manufacturing.
Detailed elucidation of plasma uses in engineering can be best demonstrated by some key examples, which testify to the transformational potential of plasma in various fields.
Plasma Arc Cutting: Here, an accelerated jet of hot plasma is used to cut through electrically conductive materials, such as steel, copper, brass, aluminium, and others. The nozzle of the cutting torch blows the plasma out as the electricity from the cutter's power supply forms the completed circuit. This high-speed plasma and compressed-gas combination slices through the workpiece, melting the material.

Biomedical Engineering: Plasma applications in biomedical engineering are gaining momentum. Cold Atmospheric Plasma (CAP) finds use in sterilisation of medical instruments and implants, treatment of skin diseases, wounds and even cancer. For instance, the shift from cauterisation to argon plasma coagulation (APC) – a non-contact method of coagulation – in medical procedures is a tremendous leap.
Electric Propulsion: Another significant example is in the field of aerospace engineering. Plasma-based electric propulsion systems are gaining attention due to their higher efficiency compared to conventional chemical rockets. An ion thruster generates thrust by accelerating ions using electricity, where plasma's property of conducting electricity is exploited. This delivers a continuous and efficient propulsion, optimising fuel consumption and mission longevity.
Indisputably, plasma provides a promising avenue for engineering, opening doors to innovative and advanced applications across a wide spectrum of fields.
Fluid mechanics, an essential branch of physics, is concerned with the behaviour of gases and liquids at rest and in motion. When these gases reach high temperatures, they transition to the plasma state, adding a new layer of complexity to their behaviour. This is where the fascinating link between plasma and fluid mechanics arises, crossing the paths of two diverse fields for a broad spectrum of engineering applications.
When we delve into the intriguing world of plasma uses, it soon becomes apparent that its link to fluid mechanics isn't just hypothetical. In fact, it forms the foundation of various engineering mechanisms. Interestingly, the theories and principles of fluid dynamics serve as guiding forces to understand plasma dynamics, shaping the tools and techniques employed in plasma engineering.
Plasma Fusion Devices: One of the most elaborate demonstrations of these links is in the field of nuclear fusion. In devices such as tokamaks and stellarators, plasma, in this case, a hot hydrogen isotope mixture, forms the primary object of focus. The core challenge lies in maintaining the stability of this high-temperature plasma. This necessitates understanding both fluid dynamics and magnetohydrodynamics, a field that treats plasma as a fluid and incorporates the influences of electric and magnetic fields on its behaviour.
In fields such as space propulsion or industrial waste management, the principles of fluid mechanics and plasma physics harmonise to create effective solutions.
Exploring concrete instances can offer a tangible understanding of how plasma's unique behaviour in fluid mechanics plays a pivotal role.
Hall Effect Thrusters: In the field of spacecraft propulsion, the principles of fluid dynamics and CFD simulations offer a means to model plasma behaviour in Hall Effect Thrusters (HETs). An HET is an ion propulsion system, where heavy ions are accelerated due to an electric field. Studying the plasma as a fluid contributes to the understanding and prediction of its behaviour, which can lead to efficiency improvements, enabling long-duration space missions.

This characteristic equips it with unique interactive capabilities with electric and magnetic fields, creating a nexus of potential applications in the engineering field.
There's an array of innovative applications that demonstrate plasma's effectiveness in engineering. Let's delve into some of these, exploring their techniques and advantages.
Plasma-enhanced Chemical Vapor Deposition (PECVD): PECVD is a process widely used in the manufacture of anti-reflection coatings and thin film solar panels. Gimelastically excited plasma decomposes reactive gases, which are then deposited on a substrate at comparatively lower temperatures. This process is vital in semiconductor and photovoltaics industries since it allows depositing layers of different materials with precise control over their optical and structural properties.
Application | Process | Benefits |
Anti-reflection Coatings | PECVD | Precise control over optical and structural properties of layers |
Plasma Electrolytic Oxidation (PEO): PEO, also known as Micro Arc Oxidation, employs plasma discharges to form oxide coatings on metals. The process vastly improves the wear resistance, thermal stability, and corrosion resistance of materials making it ideal for automotive and aerospace industries. The coatings obtained via PEO are usually hardy and adhere better to the substrate due to their peculiar microstructure, which includes interconnected micro-pores and micro-cracks.
In the rapidly evolving world of engineering, plasma is poised to play a central role in next-generation technologies, marking a bold step forward into a more efficient and sustainable future.
Space Propulsion: In the realm of space technology, advancements in ion propulsion present a future where space missions will be more fuel-efficient and sustainable.
