Marine Anti-Corrosion Coatings
While materials used in marine environments have been optimized against corrosion, surfaces still suffer from corrosion when exposed to harsh conditions of saltwater over time. One of our specialist ceramic coatings, designed specifically for harsh marine conditions and meeting the ASTM B117 standard (salt spray fog testing), is a popular option for marine manufacturers. This lightweight anti-corrosion ceramic coating adds minimal thickness, making it an excellent option for components in confined spaces. Its durability against marine salt conditions increases the lifespan of components subjected to prolonged exposure to marine environments, significantly reducing the need for replacement. In addition to its anti-corrosion properties against marine environments, it also:
- Can withstand very high temperatures
- Is suitable for a wide range of substrates, including metals, CFRPs, and some polymers
Zircotec’s proprietary plasma-applied ceramic coatings are known for their thermal barrier properties, which can also be utilized in the marine sector. Our thermal barrier ceramic coatings can be used on marine exhaust systems and diesel engines, reducing the surface temperatures of coated components and retaining heat within the exhaust, thereby improving efficiency and performance. This is commonly applied to exhaust manifolds, pipes, pistons, valves, and more. Aside from the exhaust system and engine, its thermal barrier and insulative properties can be utilized in heat recovery systems, including heat exchangers, HVAC systems, cooling systems, boiler components, and more. Our ThermoHold® thermal barrier ceramic coating is suitable for marine components commonly made out of steel alloys, cast iron, Inconel, copper alloys, titanium alloys, nickel alloys, and other metallic surfaces.

While steel and other metals remain prevalent in marine applications, carbon fibre reinforced polymers (CFRPs) are increasingly used in the marine sector as well. CFRPs are found in parts of the exhaust system, engine components, heatshields, etc., where our ThermoHold® for Composites thermal barrier ceramic coatings can be utilized. Our plasma-applied thermal barrier ceramic coatings are suitable for CFRP components used in marine environments and provide thermal barrier properties by reducing surface temperatures by up to 33% and insulating thermal energy of coated components.
Summary of Marine Thermal Barrier Coatings:
- Suitable for applications up to 1400°C
- Offer surface temperature reductions by up to 33%
- Improve efficiency by retaining heat within coated parts
- Protect surrounding components from excessive heat exposure
- Suitable for a wide range of metals, CFRPs, and some polymers
- Protect against corrosion (ASTM B117)
Our ElectroHold® DIELECTRIC ceramic coating can be used on marine components involving electronics. It helps insulate components electrically as well as protecting them from corrosion. It is commonly used on marine electrical connectors, cables, sensors, etc., offering dielectric protection and reducing the risk of short circuits and malfunctions. Its anti-corrosion properties also contribute to the improved lifespan, durability, and cost-effectiveness of these electrical components. It can be applied to various substrates, including steel alloys, aluminium alloys, copper alloys, and composites.
