Electropolishing
Surface protection that performs
We provide precision Electropolishing for stainless steel and Hardide coated components, delivering a smooth, ultra-clean surface finish that’s engineered for high-performance environments. Whether you’re targeting enhanced corrosion protection or a critical sealing interface, our electropolishing process refines your parts to meet the highest technical standards.
Enhanced performance built into the surface
Electropolishing removes a controlled layer of surface material through an electrochemical process. This eliminates embedded contaminants, burrs, micro-cracks and high points transforming rough metal into a clean, uniform, low-friction surface.
- Creates an ultra-clean surface that resists corrosion and adheres to dimensions
- Reduces surface roughness (Ra) to enable superior sealing and lower friction
- Enhances fluid flow in process-critical components
- The bacteria resistant surface improves corrosion resistance by removing impurities and surface defects
- Removes microscopic surface defects and improves the fatigue life of metal components, ensuring their durability in demanding applications
Precision-tuned for your application
We customise every electropolishing cycle to the material, geometry and performance requirements of your component. Whether you need a fine finish for a sealing surface or a visual polish for a consumer-facing part, we adjust voltage, chemistry and dwell time to achieve optimal results.
Works standalone or integrated
Our electropolishing service is available as a standalone finish or as part of a full surface treatment programme alongside Hardide CVD coatings or passivation. In many cases, electropolishing is the final step that maximises the benefit of the treatments before it.
Where surface quality meets functionality
Electropolishing with Hardide is a functional upgrade to your component with the additional benefit of aesthetic capabilities. With improved corrosion resistance, better sealing performance and easier cleaning, your parts last longer, perform better, and meet the most demanding industry expectations.
