Ceramic coating is commonly used for engines and exhausts because it protects against heat fatigue.

Ceramic coating – the protective coating for engines and industry

A ceramic coating is a coating that uses non-metallic, inorganic materials with high hardness and insulation in order to create a hard-wearing, high performance finish. Ceramic coatings have applications across a range of industries including automotive (engine parts, exhausts), industrial pipelines (to protect against corrosion under insulation or CUI), and even medicine (as coatings for implants). Ceramic coatings chemically bond to the substrate to provide a highly adhesive layer of protection.

In this article we look at the benefits and applications of ceramic coating and where to find ceramic coating specialists in Australia.


The top benefits of ceramic coating

The versatility and desirability of ceramic coating is down to its high performance properties. The top benefits of ceramic coat are:

  1. Abrasion resistance and dry lubrication – Improves overall durability of surfaces and objects and has extreme wear resistance. Very low friction finish with anti-galling properties.
  2. Thermal barrier properties – Reduces thermal fatigue, insulates machine components from heat and so extends their life span, allows higher operating temperatures, and is fire resistant (zero flame spread) and heat tolerant up to 1500°C.
  3. Waterproof and chemical resistance – By providing a bonded layer, ceramic coatings are waterproof and impermeable. The effectiveness of these coatings against CUI is due to its adhesion, waterproofing and thermal barrier properties.
  4. Electrically insulating or conducting – Ceramic coatings are used as dielectric coatings to electrically isolate parts at different voltages.
  5. Long-lasting – With superior adhesion, high levels of resistance to heat, chemicals, , wear, and impact, it is no surprise that ceramic coatings are some of the longest-lasting coating options available.

The ceramic coating process and applications

The inorganic component of ceramic coating can be a number of materials including chrome oxide, zirconium oxide, titanium oxide, aluminium silicate and more. The most common ceramic powders include aluminium oxide, titanium dioxide and chrome oxide. Depending on the type of ceramic coat used, there are a variety of application methods that are utilised. Techniques include roller application, airless spray, brush, dip spin, and thermal spray coating such as plasma spray – a coating process where a melted or heated material (the ceramic powder) is sprayed onto a surface. This versatility lends itself well to the range of applications that use ceramic coatings.

Ceramic coating exhaust systems protects from metal fatigue and corrosion.

Ceramic coating engine parts and exhaust systems protects from metal fatigue.

Automotive ceramic coating for exhaust system and engine parts

Ceramic coatings are ideal for metal surfaces that need to be protected from heat, abrasion, and chemicals, and so the automotive coating industry is a perfect place to use them. Particularly under the bonnet and in the underbody of a vehicle. Piston heads/sleeves, exhaust systems, headers and downpipes, valves, and combustion chambers, are just a few of the surfaces that benefit from the reduction in temperature and thermal shock with ceramic coat.

Ceramic coating motorcycle exhaust systems and engine components is also possible and improves the overall performance of the engine. A ceramic coat decreases the need for maintenance and prevents overheating components and metal fatigue.

Industrial ceramic coating – pipelines, CUI, and infrastructure

Ceramic coating is used to protect planes, chemical plants, pipelines, power plants, bridges, and infrastructure from corrosion, heat, and chemical attack. While the rates of failure for pipelines in Australia are lower than those in Europe or America (about 10-20% of the average rate), Australia’s pipelines are also younger and as time marches on so does corrosion. CUI is an invisible attacker, often not discovered till it is too late. Protection of insulated surfaces with ceramic coating can help prevent this problem. The heightened impact resistance and general strength of ceramic coatings is also suited to coating wind turbine blades to prevent leading edge erosion.

Ceramic coating suppliers in Australia

If you are interested in ceramic coating, Australia has companies and applicators specialising in their application. From Sydney to Perth you can find what you are after, from ceramic coating engine parts to mining components. As for ceramic coating prices, there are a range of variables affecting what an applicator may charge. For the ceramic coating exhaust cost, a 4 cylinder exhaust manifold may cost $150, up to $250 for a V-8, but this also depends on ceramic coating type and regional variations. Below are the links to local ceramic coating supplier pages including information on where to find a ceramic coating specialist near you.
