Generally, when modifying an engine for greater performance gains, the process usually increases STRESS on the parts. Along with our precision machining and high quality assembly, We offer a COMPLETE line of Performance Chemical Coatings. These coatings perform a variety of functions, but also they eliminate/minimize stress. A stress-free engine produces more horsepower!!

Now, in addition to our full line of internal coatings, we offer an external coating for exhaust manifolds and headers. The process will include degreasing and media blasting of the parts. Then an internal Thermal Barrier coating is applied. Next, two coats of "Cast Iron Gray" are applied to the outside of the parts. No more flaking paint, or rusting parts! And they look great as well!

The charge for this complete process is generally only $95.00 per side!!

· Thermal Barrier coating for piston domes, combustion chambers, valve faces, and exhaust ports.

· Solid Film Lubricant coatings for piston skirts and pins, valve stems, rod, main, and cam bearings.

· Oil Shedding Thermal Barrier for cranks, rods, and windage trays.

Performance Coatings fall into four general categories. They are: Dry Film Lubricants, Thermal Barrier coatings, Thermal Dispersants, and Corrosion and Chemical Resistant coatings. It should be noted that some coatings will fall into more than one category. You might have, for example, a Corrosion Inhibitor that is a Thermal Dispersant. Also, we can use both a Thermal Barrier on the valve head, and Dry Film Lubricant on the valve stem. The treated valve is on the left!

Dry Film Lubricants: Dry Film Lubricants, also known as solid film lubricants, provide a lubricating film that reduces friction, inhibits galling and seizing and in some instances can aid in dispersing heat. The appearance is generally a charcoal gray and takes on a sheen upon burnishing. They are slippery and provide an extremely low coefficient of friction.
One of the obvious reasons for using a lubricating coating is to reduce friction, which improves wear, extends part life and frees up HORSEPOWER that is usually lost to friction. A second major benefit is a reduction in part temperature. This is especially important to such parts as valve springs! Here the pigment choice is critical as certain ingredients can trap heat in a part. Not all coatings are created equal!!

Thermal Barrier Coatings: Thermal barrier coatings ( TBC ) are designed to reduce the movement of heat. In some instances, such as exhaust systems, you want to keep the heat WITHIN the part. In combustion chambers you want the heat generated by combustion to push down on the piston rather than bleed off into surrounding surfaces. Due to continued testing we are learning that simple thremal barrier action is not the only characteristic that is important. In fact, certain 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 part! And here at MRX Motors we can make the proper choice for your application!!

Here we have a pair of Diamond Ultralight pistons that have been treated with both a Thermal Barrier Coating for the crown, and a Dry Film Lubricant for the entire skirt area!!

Thermal Dispersants: Being able to move and control heat is of tremendous importance. Excessive temps can lead to metal fatigue, boiling fluids, damaging metal expansion, reduced 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. Individual products such as TLTD can be utilized by themselves or in conjunction with other coatings to manage the flow of heat. TLTD is capable of transferring heat FASTER then the bare metal surface. While TLTD does make use of the color black, TLTD is more than a simple "black body" heat emitting coating. TLTD 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 brakes, intake manifolds, cylinder heads, oil pans, radiators, intercoolers, and .... MORE!!
Certain TECH LINE Dry Film Lubricats are capable of reducing part temps not only thru the reduction of friction but also thru increased thermal flow. The active ingredients accelerate the movement of heat. This is especially beneficial on valve springs where excess heat can lead to accelerated fatique and breakage!
