Lubricity Research


In the early stage development of this company a number of avenues were taken to explore possible application/uses for the material that was being produced. One of those avenues was determining its use in various lubricants. This application was pursued because of the spherical characteristic of CNOC, that somewhat resembles ball bearings with pi orbital clouds on the exterior like highly lubricative graphite.

Before professional testing was initiated, a regimen of what we called “backyard” testing was performed to test GNO’s lubrication possibilities. One of the first tests involved a 2-cycle weed blower engine. The results proved to be very positive. A number of other simple additive tests were performed: smoking auto engines were rendered “non-smoking”, powerless diesel engines regained their horsepower.

Based on the above results, it was determined that the CNSC material should be submitted for professional testing and documentation. The petroleum department of the prestigious Southwest Research Institute, San Antonio, TX, was selected to perform a series of objective tests as to the lubrication properties of CNOC material.

Samples of an off-the-shelf, SEA certified motor oil were prepared for testing. Three control groups of the motor oil were prepared: three samples of a .5% solution, three of a 1% solution, and three of a 3% solution. Each was tested by approved ASTM lubrication procedures.

The ASTM testing Covered:
D5183, Coefficient of Friction:

The important final numbers, for the Coefficient of friction, concern “incipient seizure”
D3233A Falex and Vee-Block

The Falex and Vee-block test concern “load Factors”, a combination of pressures and friction.
D2783 Extreme pressure Four-ball

The important final numbers for the Extreme pressure four-ball test, concern “wear index load”, Weld point”, and Last Non seizure Load”.

The first round of testing was to determine which of the 3 chosen dilutions (a guess, some place to start) was to give a base-line solution to move into the next phase of testing. A .5 % dilution, a 1%, and 3% dilution were chosen. There was no basis for pre-guessing any dilutions. An SEA grade of off-the-self motor oil was chosen, and the 3 dilutions were then subjected to the ASTM lubricant testing.

In almost all of the testing, the .5 % dilution performed the lowest, followed by the 3 %. The standout, and superior results delivered were from the 1 % dilution. The 3 % performed better than the .5 %, and only a couple of times did the 3 % perform close to the 1 %.

For instance, the ASTM D2783, Extreme Pressure Four-Ball, test on the 3 solutions where the true load for the .5 % was 1572, compared to the true load of the off-the-shelf motor oil of 1876. The .5% solution performed less than the off-the-shelf oil. The 3% solution true load was 1948 (which was better than both the .5% solution and the off-the-shelf standard). The 1% solution bettered the other 3 with a true load of 2050. Almost all other tests followed these basic test results. The results of the 1% solution in motor oil were remarkable – a significant increase in lubricity.

The one percent solution increases the incipient seizure point by 13%, the weld-point by 20%, and last non-seizure load also by 20%.

After achieving the results reflected above, it was decided to run further tests to see how this 1%  dilution would perform on other types of accepted lubricants. Gear oil, ATF oil, and 2-cycle engine oil was chosen to be tested with a 1% solution. There was a 14% increase in “lubricity” with the AFT oil; the gear oil test was inconclusive, probably due to poor mixing with such dense oil, and the two cycle oil did not show any differences in this one type of particular test.
