The idea of coating a surface with another substance is nothing new. Jewellers have been plating cheaper metals with gold and silver for centuries, and many grandmothers have cooked with enameled crockery since cast iron became popular.
Coating technology has advanced rapidly, and we now have the ability to coat almost any substrate with almost any material imaginable. From ceramics to metals and superconductors, thin film technology is indispensable in many industries, and its role in future advancements is certain. The only question is how.
Uses of Thin Films Today
Manufacturers use thin films to alter or enhance the properties of an existing substrate or combine several coatings for unique effects. The common uses of thin films today include:
- Hard coatings for cutting tools
- Corrosion protection
- Highly reflective coatings for laser mirrors
- Anti-reflective coatings for optics
- Photodetectors in infra-red devices
- Active and passive thin-film elements in electronic components
- Integrated circuits
- Friction reduce
- Coatings and adhesives in manufacturing
- Liquid or gas sensors
- Biocompatible implant coatings
- Photovoltaic coatings for solar panels
- High-purity semiconductors
Almost any field including medicine, magnetics, and alternative energy, takes advantage of the benefits that thin-film technology provides.
An Overview of Current Research
Thin film technology plays a massive role in cutting-edge research by allowing researchers to alter the properties of existing materials in a highly-controlled and granular manner.
Advances in nanotechnology, photovoltaics and energy storage, medical devices, and electronics would have been impossible without the ability to lay down multiple layers of atom-thick coatings.
While most of the major problems facing thin film deposition technology are resolved, plenty of space still exists for innovation.
Computer simulations are becoming a staple in thin film deposition, where a manufacturer can model the entire process and outcome before going ahead with physical experimentation.
Novel modeling techniques such as multiscale and hybrid methods allow researchers to combine different simulation methods into one technique, speeding up the modeling process and improving its accuracy.
Future of Engineering in Five Years
Modular deposition systems are likely to become more common as the need for rapid prototyping increases. These modular systems allow researchers and small manufacturers to adapt to changing strategies and materials without buying another deposition system or retooling their existing one.
It’s also likely that engineers will continue to refine thin film technology, producing higher utilization rates while reducing energy use and carbon emissions.
By increasing the durability of consumer electronics, optical displays, and mechanical components, manufacturers can move away from wasteful processes and move towards more sustainable, eco-friendly products that will last longer and be more affordable to produce.
Thin-film technology has already replaced many polluting coating methods in the automotive industry, and advances in speed and consistency will mean that more manufacturers will pivot to sustainable thin-film processes.
Final Thoughts
Thin film technology has already made a massive impact and sped up advances in fields such as engineering, optics, electronics, and medicine. It offers an exciting and sustainable alternative to environmentally harmful plating techniques while helping manufacturers cut costs and increase output. The future is bright for thin-film technology, and we can’t wait to see what it brings.
