Coatings

Dry Film Lubricant HM-30: ...more >>

Bearings are not the only part that will benefit from being coated with HM-30. Crankshafts, pistons, and other engine parts also perform better when coated. The HM-30 coating reduces friction, provides a more durable surface and reduces wear.

HM-30 is also used extensively on automotive fasteners and in many other commercial applications where reducing friction and/or a more durable surface is necessary.

Teflon Coating: ...more >>

The most common lubricating element in our custom precision coatings is polytetrafluouroethylene, or PTFE. Only PTFE offers the lowest coefficient of friction, is stable and effective throughout a wide temperature range, and is inert to chemical attack. Because of it's low surface tension, PTFE is an excellent release agent. It is even approproved for use in food contact applications. Other effective lubricating elements include fluorinated ethylene propylene, or EFP, and perfluoroalkoxy, or PFA. Both offer excellent non-stick and non-wetting characteristics and outstanding abrasion resistance. Coating materials are suspended in a compatible carrier such as solvent or water, so that they may be applied using conventional painting techniques.

The result is a thin, continuous barrier of protective film that will resist chipping, spalling, abrasion, cold flow, temperature extremes, weathering, and a broad range of corrosive environments.

Typical Benefits and Applications:

Friction and wear resistance - Machine parts and components, automotive parts and components, compressors
Eliminate wear - Sliding mechanisms
Superior release - Molds, forms & other equipment requiring non-stick properties
Chemical resistance - Valves, pump components, knife gates, rubber pinch valves
Corrosion resistance - Fasteners, flanges, machine parts

Phosphate coating: ...more >>

Phosphate coating is especially effective where it is desirable to reduce friction, galling, and scoring on ferrous surfaces. Phosphate coating reduces wear and is lubricative, which facilitates break-in of bearing surfaces. It has an unprecedented degree of thermal stability, inhibits corrosion, and creates a superior substrate for paint and other industrial finishes.

Phosphate coating's sponge-like surface holds oil to create a continuous film between moving metal parts, thereby making an outstanding break-in medium. High strength bolts that were tested repeatedly at 13,800 foot pounds of torque did not gall (more than 120,000 PSI of stress).

Typical applications for phosphate coating include:

Gears
Bearings
Fasteners
Actuators
Cynlinder sleeves
Sprockets
Marine components

Ceramic Heat Shield - HS-44: ...more >>

This coating repels the heat and keeps the outside of parts such as heads, cylinders and motorcycles pipes cool. The Harley-Davidson head and cylinder on the right were coated with Midnight Black Wrinkle Powder, and the combustion chamber, valves, and exhaust port are coated with our exclusive HS-44 ceramic coating. This coating repels the heat back into the chamber where it is needed to make the power. The same coating can be used on piston tops. This creates a thermal barrier and is designed to keep the heat out of the piston and reflect it back into the chamber.

Because the piston and head are manufactured of aluminum, both act as a heat-sych, absorbing heat from the combustion cycle, causing the piston to expand at a much greater rate than the cylinder and resulting in the loss of piston-to-wall clearance and could even seize the piston.

To prevent this, we have two coatings that we use on pistons: HS-44 and HM-30. Using these coatings allows tightening of the piston-to-wall clearance without fear of sticking the piston. This also keeps the piston straighter in the bore for better ring seal and will help the engine last longer.

These same coatings are used on exhaust pipes as well. The first coat gets cured at 800 degrees F and the second coat at 750 degrees F. The pipe is then burnished with ceramic beads for 30 minutes for a chrome-like finish that will not tarnish from overheating.

For those who prefer black exhaust pipes, we also have a wonderful high temperature black coating called Black Iron, which is added on top of our HS-44 for maximum thermal protection. This coating has a little texture to it, a small amount of shine, is extremely durable and provides the same amount of heat shield as the chrome-like coating.

We have also developed a coating for the inside of chrome pipes to prevent unsightly blue tarnish from building up on the outside. The chrome on the outside is completely protected during cleaning and coating.

We are currently developing a coating that can be mixed with different colors of pigment to produce the same thermal protection but with a much wider selection of colors from which to choose.

With all of these exciting coating options, it makes sense to choose h.m. elliott, inc. for all of your coating needs for your engine or custom bike.
