If you’re new to the world of engineering coatings, then you’re probably asking how corrosion protection coatings stop metal from rusting. It can be hard to imagine that just a thin layer of coating can completely transform the corrosion resistance level of a component.
Well, we’re here to clear it all up for you!
There is no denying the fact that corrosion is one of the biggest threats to our metal components. It causes mass destruction, failure, long-term degradation, and not to mention, costly replacements.
Numerous industries are battling with the effects of corrosion. Whether it be in industrial machinery, infrastructure, or transportation, the need for effective corrosion protection is felt far and wide. No industry or operations should fall short on performance or longevity due to corrosion.
That’s why we at Alphatek have developed coating solutions that prevent rusting and intend to improve the lifespan of your metal surfaces. In this blog, we will explain exactly what corrosion protection coatings are, why we use them, and how we can stop rusting from impacting various industries.
Understanding Corrosion Protection Coatings
Corrosion protection coatings are specially formulated layers applied to metal surfaces to shield them from environmental factors that cause oxidation and rust. These coatings act as a barrier between the metal and elements such as moisture, oxygen, and chemicals, all of which accelerate corrosion.
There are different types of corrosion protection coatings, including:
- Metal Spray Coatings – Thermal spraying techniques apply protective metal or alloy coatings to enhance corrosion resistance.
- Fluoropolymer Coatings – Non-stick and chemically resistant coatings that protect against harsh environments.
- Zinc and Aluminium Coatings – Sacrificial coatings that corrode before the underlying metal, providing long-term protection.
- Epoxy and Polymer Coatings – Protective layers that create a non-permeable shield against moisture and chemicals.
At Alphatek, our proprietary thermal spray coatings are designed to provide superior protection, ensuring that components remain rust-free even in the most demanding conditions.
Why Are Corrosion Protection Coatings Used To Stop Metal From Rusting?
Did you know, the global economic impact of corrosion is estimated at around £1.9 million?
Corrosion protection coatings are widely used across industries to maintain the integrity, functionality, and appearance of metal components. Some key reasons for using these coatings include:
- Extending Component Lifespan
Rust weakens the metal, leading to premature failure. Protective coatings prevent corrosion, extending the service life of equipment and infrastructure.
- Reducing Maintenance Costs
Without protection, corroded metal requires frequent repairs or replacements. Coatings minimise maintenance expenses by preserving metal integrity.
- Enhancing Safety and Performance
Corroded structures and machinery pose safety risks. Industries such as aerospace and oil & gas rely on corrosion-resistant coatings to maintain operational reliability.
- Improving Aesthetics and Functionality
In industries like automotive and marine, coatings not only prevent rust but also improve appearance and aerodynamics.
How Corrosion Protection Coatings Stop Metal From Rusting
Corrosion protection coatings work through various mechanisms to prevent rust formation:
- Barrier Protection
Many coatings, such as polymer-based or fluoropolymer coatings, create an impermeable barrier that prevents moisture and oxygen from reaching the metal surface. Without these elements, rust formation is halted.
- Sacrificial Protection
Zinc and aluminium coatings act as sacrificial layers, corroding before the base metal does. This method is widely used in galvanising and thermal spray coatings for long-term protection.
- Electrochemical Prevention
Some coatings utilise electrochemical properties to prevent rust. These coatings modify the metal’s electrical potential, making corrosion less likely.
- Chemical Resistance
Specialised coatings, such as fluoropolymer coatings, protect against aggressive chemicals, acids, and salts that accelerate corrosion in industries like chemical processing and marine applications.
