Ceramic Thermal Barrier Coating

Ceramic coating is an excellent thermal barrier.

Ceramic thermal barrier coating.

The most advanced exhaust system coating available. Except yttria stabilized zirconia other materials such as lanthanum zirconate and rare earth oxides are also. The coating insulates the substrate material and lowers the substrate temperature. This paper summarizes the basic properties of ceramic materials for thermal barrier coatings.

Zircotec uk s largest thermal barrier ceramic coating offerings paul hilier 2020 08 11t14 55 15 00 00. Thermal barrier coatings with novel architectures for diesel engine applications. They are specifically designed to reduce heat loss from engine exhaust system components including exhaust manifolds turbocharger casings exhaust headers downpipes and tailpipes. Thus it is a promising ceramic thermal barrier coating material for aero gas turbines and high temperature applications in metallurgical and chemical industry.

Thermal barrier ceramic coatings are becoming more common in automotive applications. Low thermal conductivity thermal barrier coatings tbcs are preferred as they can increase turbine engine efficiency lower costs reduce emissions and increase durability. Thermal barrier coating tbc is a coating made of ceramic materials deposited on the surface of a high temperature resistant metal or superalloy. Ceramics in contrast to metals are often more resistant to oxidation corrosion and wear as well as being better thermal insulators.

Dan and his ceramic engineering brothers perfected this technology in both their own nascar modified and with leading nascar winston cup teams. Devices such as engine turbine blades can operate at high temperatures and can increase the thermal efficiency of devices engines etc by more than 60. By doing so ceramic coating reduces under hood heat temperatures which will increase horsepower. It is a very durable ceramic reinforced coating available in a variety of colors.

In the early 1970 s ceramic engineer dan swain developed the first successful ceramic thermal barrier coating for internal engine use. Tungsten grey ceramic coated manifolds. A 30 reduction in thermal conductivity translates into an approximately 100 c increase in temperature difference across a 200 µm thick coating. The sealing layers used were the metallic m and the ceramic thermal.

A sealing layer over the top coat was also applied to prevent fuel and combustion gases entering the pores of the ceramic coating which may cause engine performance losses 5 6 8 11. This process is also known as exhaust heat management when used under bonnet these have the positive effect of. Keco has been supplying high performance coatings to leading lighting manufacturers for over 25 years. Keco s thermal barrier coatings are heat resistant up to 1200º f continuous.

We are specialists in heat management. Our coatings are specified to satisfy the most demanding applications for industries such as food processing marine corrosion resistant and thermal barrier.
