First by impregnation of
the skirts, pin bores and ring area with a dry film coating, reducing the
effects of piston scuffing, piston rock and other friction induced
problems. Finally, the underside of the piston is coated with a thermal barrier. This process evenly distributes heat in the chamber, thereby greatly diminishing or eliminating the chance of detonation, while reducing oil cling.
A leading manufacturer of ring and pinion sets and transmissions conducted a test using parts coated with dry film lubricant. Temperature drops of up to 40 degrees and increased gear life were observed. Lower gear & oil temperatures will reduce backlash, shock loading and gear cracking.
Impregnation with dry film lubricant (no dimensional change) provides substantially improved bearing life, while at the same time reducing 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. normally lost to friction. A second major benefit is a reduction in part temperature.
By applying thermal barrier to the bottom of the intake and any open crossovers, we reduce heat transfer from the oil galley. The exterior of the intake manifold gets a heat dispersant coating to aid in cooling. Intakes can also be Cermachromed™ for a show finish.
Dry film impregnation of valve stems/seats will greatly reduce stem and seat angle wear. Valve faces receive a coating of ceramic barrier to provide additional heat protection. Both coatings aid in shedding carbon, resulting in higher flow rates over the life of the engine. Valve springs usually fail because of heat related problems. Through the application of a heat dispersant, we can substantially increase spring durability while maintaining spring rates longer.
Thermal barriers applied to a turbo provide more consistent boost by keeping the heat in the system. Impellers that are dry film impregnated see considerably improved life because the coating can withstand temperatures as high as 4500 degrees Fahrenheit.
Oil pump gears, plates and passages coated with dry film lubricant will provide increased oil volumes. Additionally, less heat will be produced because of reduced friction.
These parts typically do not have a pressure fed lubricating system. By coating with a dry film lubricant, wear will be significantly reduced resulting in more consistent valve timing.
Many other accessories such as rear end housings, hood hinges & springs, shock towers, pulleys, brackets, oil pans, timing covers and many other parts can be coated with Chromex™ for the polished aluminum look or any of our other coatings for a durable and attractive finish.
