Sophisticated high heat coatings were developed in the aerospace and nuclear industries, where they have been used extensively to prevent critical components being damaged by extreme heat. Combinations of ceramic and metallic plasma sprayed coatings can provide corrosion and temperature resistance up to an astonishing 1400oC, with no discoloration or degradation.
These lightweight and durable plasma sprayed ceramic coatings, which bond inseparably to the substrate, provide highly effective thermal barriers on exhaust systems, turbos and brake elements, yielding simple and effective performance upgrades.
They effectively prevent heat transfer, which results in an increase in power and improves throttle response by retaining heat in the gas flow, achieving
- Higher gas speeds
- Better engine scavenging
- Reduced turbo lag
- Lower back pressure
- Faster gas pulsing
- Reduced heat input to other components
A typical 25°C drop in under bonnet temperature results in decreased intake temperatures which can give up to a 5% increase in power and significantly increases ancillary reliability.
Brake elements can be coated on various faces, which reduces heat transfer into the brake fluid. For high performance vehicles and rally cars that undergo significant heat cycles with disks glowing red hot under harsh braking conditions, ceramic coatings can be applied to deflect heat away from critical areas.
- Woof TMT coatings are proven to drastically reduce surface temperatures by up to 30%
- Plasma ceramic coatings can withstand temperatures of up to 1400°C
- Reductions of up to 160°C on surface temperatures are achievable
NOTE: Ceramic coating technology has been extensively tested by MIRA (Motor Industry Research Association) to establish the effectiveness of these types of coating in terms of performance enhancement.
