Test Results- All engine components visually looked new.
- Ring liner interface showed some signs of wear.
- Bearings show little or no wear.
- Oil sump temperature at full load condition 315°F
- Engine coolant temperature at full load condition 218°F
- Exhaust gas temperature at full load condition 1430°F
- Peak cylinder pressure at full load condition 2900 psi
Friction and Wear Coatings
-
Today's coatings have been developed for a dual purpose:
- Solid lubricant to be used with or without lubricant
- Tailored heat transfer
- Coating is applied by spraying, dipping, or brushing.
- Thickness range of 0.001 in. to 0.020 in.
- Friction coefficient dry µf <0.12, dry wear rate <0.1gm/hr
- Coating in cylinder bore yields 6.5% improvement BSFC
- Can be applied to most metallic substrates

Thermal Barrier Coatings (TBCs)
The peak development of thermal barrier coating (TBC) technology as adapted to the modern day diesel engine occurred in the mid 1980’s. Since our inception in 1984, Adiabatics Technologies, with the support of U.S. Army TACOM, has played a key role to promote the development of the LHR diesel engine.

Polymer-Based Thermal Barrier Coatings (TBCs)
Recent advances in polymer technology have increased the capabilities of polymers to withstand higher temperatures. Because polymer thermal barrier coatings (TBCs) have increasingly higher temperature capabilities, they are finding more uses in today’s advanced technology fields. These polymers bond to a wide range of substrates. In addition, the silicone polymers we have chosen to investigate have a high thermal expansion coefficient and can remain bonded to substrates because of their flexibility over a wide temperature range.
