Ceramic coatings fall into 4 general categories. They are :
- Dry Film Lubricants Coatings 
- Thermal Barrier Coatings
- Thermal Dispersant Coatings
- Corrosion & Chemical Resistant Coatings

Dry Film Lubricants Coating
Dry Film Lubricants Coating also known as Solid Film Lubricants Coating. It provide a lubricating film that reduces friction, inhibits galling and seizing and in some instances can aid in dispersing heat. It's slippery and provide an extremely low coefficient of friction.
The 2 most important components are the binders and lubricating ingredients. Without a good binder the coating will not stay in place and will simply cold flow or buff of in operation. Similar coatings using the same pigments but different binding systems can show a wide variation in load carrying abilities, ranging from 100,000 psi to over 350,000 psi. The pigments determine the actual lubricating potential. PTFE (Teflon), as example, is listed as having the lowest coefficient of friction (COE). However, under high speed and load, the COE of PTFE degrades while that of MOS2 (Moly) improves, until it is significantly better than PTFE. Selecting the proper ingredients can make or break a coating.
One of the obvious reasons for using a lubricating coating is to reduce friction, which improves wear, extends parts life and free up H.P. normally lost to friction. A second major benefit is a reduction in part temperature. This is especially important to such parts as valve spring. Here the pigment choice is critical as certain ingredients can trap heat in part.

Thermal Barrier Coatings
Thermal Barrier Coatings are designed to reduce the movement of the heat. In some instances, such as exhaust systems, you want to keep the heat within the part. In combustion chambers you want to use the heat generated by combustion to push down on the piston rahter than bleed off into surrounding surfaces. Due to continued testing we are leaning that simple thermal barrier action is not the only characteristic that is important. In fact TBC's will move an engine into detonation. TBC coatings can be made from a variety of materials. Ceramics get the most attention, though there are other materials that are superior in specific applications. The proper choice is critical to the overall function of the coating.

Thermal Dispersant Coatings
Being able to move and control heat is of tremendous importance. Excessive temperature can led to metal fatigue, boiling fluids, damaging metal expansion, reduce electrical efficiency and a host of other problems. Traditionally dealing with heat has been handled either by expanding the radiating surface, constructing parts from materials that are more heat conductive and using the color black. With advances in thermal management methods additional ways of enhancing heat transfer now exist. Thermal Dispersant Coatings can be utilized by themselves or in conjuntion with other coatings to manage the flow of heat. TDC is capable of transferring heat faster than the bare metal surface. While TDC does make use of the color black, TDC is more than a simple 'black body' heat emitting coating. TDC includes ingredients that also contribute to increased heat flow. Combining these properties with increased corrosion protection and the thin film application technique, maximizes thermal transfer capabilities. Effective on Braking system, Intake Manifolds, Cylinder Heads, Oil Pans and, Conrods and ....more.

Corrosion & Chemical Inhibiting Coatings
The lost of effectiveness, reduction in part life and deteriorating appearance due to corrosion/chemical damage is of real concern. Loosing a well matched/tuned header to rust is not only expensive, but frustrating. A good aluminium manifold can become junk if the water inlet area corrodes excessively. Keeping components clean and attractive is of concern when promoting your vehicle or the parts you manufacture to potential sponsors or customer.
