EV Thermal barrier coatings (TBCs) are advanced materials systems usually applied to metallic surfaces operating at elevated temperatures, such as gas turbine or aero-engine parts, as a form of exhaust heat management.
These hundred μm to two mm thick coatings of thermally insulating materials serve to insulate components from large and prolonged heat loads and can sustain an appreciable temperature difference between the load-bearing alloys and the coating surface.
In doing so, these coatings can allow for higher operating temperatures while limiting the thermal exposure of structural components, extending part life by reducing oxidation and thermal fatigue.
In conjunction with active film cooling, EV TBCs permit working fluid temperatures higher than the melting point of the metal airfoil in some turbine applications.
Due to increasing demand for more efficient engines running at higher temperatures with better durability/lifetime and thinner coatings to reduce parasitic mass for rotating/moving components, there is significant motivation to develop new and advanced TBCs.
The material requirements of TBCs are similar to those of heat shields, although in the latter application emissivity tends to be of greater importance.
The Global EV Thermal barrier coating market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Recent Indian Developments in Thermal Barrier Coatings For Jet Engines
It has been couple of decades since India embarked on a project to build a modern low-bypass turbofan jet engine compatible with the Light Combat Aircraft (Tejas) at the Gas Turbine Establishment (GTRE) of the Defence Research & Development Organization (DRDO).
The engine under development, named Kaveri, has faced multiple hurdles both technological and bureaucratic over the years.
Nonetheless, the Defence Metallurgical Research Lab (DMRL), a lab under DRDO, has produced and proven a new thermal barrier coating (TBC) material that has a maximum surface temperature capability of 1200°C. This development, as shall see, provides a useful baseline for the progression of jet engine technology in India.
A well-known producer of high-performance coatings for several sectors, including the automobile industry, is Sherwin-Williams.
The Polane T High-Temperature coating is one of their products in the EV thermal barrier coating market. In order to provide superior thermal insulation qualities for electric car battery enclosures and other high-temperature applications, the Polane T coating is a two-component, urethane-based coating.
It offers great adhesion to a range of surfaces, including metals and plastics, and can resist temperatures of up to 400°F (204°C). Critical components in EVs are best protected by the Polane T coating since it is made with a special combination of resins and additives that offer exceptional resistance to heat and corrosion.
The coating's superior UV resistance also aids in maintaining its functionality and look over time. Reduced heat transmission in EV battery enclosures is one of the Polane T coating's primary advantages.
This is crucial for EV makers since battery performance and longevity can be negatively impacted by high temperatures.
Electric vehicle (EV) makers can enhance battery performance and lengthen battery life by coating battery enclosures with Polane T to help limit the amount of heat that is transported to the battery cells.
Sherwin-Williams Polane T High-Temperature Coating is a high-performance thermal barrier coating that is created to offer crucial components in electric cars strong thermal insulation capabilities as well as protection against heat and corrosion.
It is a great option for EV makers that want to increase battery performance and longevity due to its capacity to assist in reducing heat transmission in battery casings.
For electric vehicles (EVs), Dow Corning, a division of Dow Inc., provides a selection of heat barrier coatings. The Dow Corning TC-3040 Silicone Coating is one of its most well-liked products in this group.
In order to shield and safeguard EV battery systems, power electronics, and other high-temperature components, Dow Corning developed the TC-3040 Silicone Coating, a high-performance, thermally conductive coating.
It is a low viscosity, two-part silicone elastomer that is simple to apply to a range of surfaces, including metal, plastic, and ceramic.
The Dow Corning TC-3040 Silicone Coating's resistance to extreme temperatures is one of its main advantages. It is perfect for use in EV battery packs and other high-heat applications because of its maximum working temperature of up to 250°C.
The coating can also offer good protection against corrosion and other types of deterioration, and it is very resistant to thermal shock. The Dow Corning TC-3040 Silicone Coating also has strong electrical insulation qualities, which can aid in keeping EV systems from experiencing electrical shorts and other problems.
It is a great option for use in electrical insulation applications due to its high dielectric strength and low dielectric constant.
For EV battery systems and other high-temperature components, the Dow Corning TC-3040 Silicone Coating is a high-performance thermal barrier coating that can offer outstanding protection and insulation.
It is a great option for usage in a range of EV applications because of its capacity to tolerate high temperatures, resist thermal shock, and provide superior electrical insulating capabilities.
