Metal finishes are essential in the defence industry, where components must operate reliably under high stress, shifting temperatures, and prolonged use. These treatments support performance by improving wear resistance, reducing friction, and helping parts achieve long service lifespans. They also ensure equipment remains dependable in operational environments.
1. Hard chrome
Hard chrome plating remains one of the most established surface treatments for defence equipment. Its durability and resistance to corrosion make it suitable for high-load components, such as hydraulic actuators and weapon mechanisms. Examples of advanced formulations are available from companies such as www.poeton.co.uk/advanced-treatments/apticote-100-hard-chrome-plating/.
2. Electroless nickel
Electroless nickel plating is another widely used option, appreciated for delivering an even coating on complex geometries.
3. Anodising
Anodising continues to be important in aerospace, where aluminium structures require additional surface protection. Industry research highlights ongoing demand for these finishes, with the global metal finishing chemicals market size expected to reach $13.52bn this year.
4. Thermal spray
Thermal spray coatings offer excellent resistance to heat, abrasion, and impact, making them suitable for turbine blades and other high-temperature components.
5. Phosphate
Phosphate coatings remain valuable during assembly and storage, providing improved lubrication and baseline corrosion resistance for steel parts.
Across these applications, chrome plating continues to be a consistent choice due to its ability to withstand demanding mechanical conditions. By incorporating a combination of suitable finishes, defence manufacturers can support the longevity, reliability, and operational safety of critical equipment used across military environments, ensuring performance remains stable even under extreme pressures, abrasive forces, and changing operational challenges.
