Cerflon® HFRR (High Frequency Reciprocating Rig) Tests The following HFRR tests were conducted in 2004 and show “Coefficient of Friction” measurements with Cerflon® in oil alone and also with and without anti-wear additives and friction modifiers at varying temperatures. They were conducted on both steel and ceramic materials and the results speak for themselves, especially with the ceramic.

HFRR is a micro processor-controlled reciprocating friction and wear test system that provides a fast, repeatable assessment of the performance of fuels and lubricants. It is particularly suitable for boundary friction measurements of engine oils, greases and other compounds. It is also used for boundary friction coefficient measurements for automobile fuel economy modeling.

HFRR was developed in consultation with a major fuel additive manufacturer and the Tribology Laboratory of Imperial College, London, there are currently over 400 systems in use in more than 40 countries worldwide.

There are 2 formulations, 1 & 2 FM: Friction modifier FM: Friction modifier AW: Anti-Wear additive AW: Anti-Wear additive Form: Formulation Form: Formulation s: solids s: solids All temperatures are Celsius All temperatures are Celsius The COF scale on the left side of the slide is in increments of.02 starting at the bottom on the second line and goes up to.16 The COF scale on the left side of the slide is in increments of.02 starting at the bottom on the second line and goes up to.16 The yellow line copy reads “no other FM” even though it looks like it belongs with the green line. Same with the green line copy. The no AW and no FM go with the green line and so on. What it shows is that AW and FM can be removed from the oil (lime green line) and get performance with only Cerflon® equal to fully formulated Mspt race oil. Then the dark green line shows the best results with Cerflon in Mspt Formulation 1 at higher temperatures.

The next slide, HFRR DLC, “Diamond Like Ceramic”, is a material used in extremely high performance motor sport applications on the wear points of an engine. The next slide, HFRR DLC, “Diamond Like Ceramic”, is a material used in extremely high performance motor sport applications on the wear points of an engine. The DLC surface is extremely smooth so that almost nothing will stick to it. The DLC surface is extremely smooth so that almost nothing will stick to it. The DLC material appears to benefit even more than the steel material with the addition of Cerflon® to the “Motor Sport Formulation 1”.
