ll0YAL 0ClE'l'Y lll UIIVERS FACTS 0F lllilC'l'llI N MAY 1952, The Royal Society published reports prepared by a number of the worldis leading scientists who had been studying the cause of wear due to friction and problems of lubrication. Their findings proved that formerly acceptable theories of lubrication were based on false premises. Many years ago it was discovered that even the most highly polished surface when viewed under a powerful microscope showed jagged peaks and valleys. During the experiments described by the Royal Society, it was discovered that flash temperatures of up to 1832017 occurred where these peaks met. These: flash temperatures were photographed and computed by sliding a metal surface over a glass plate. The infa-red rays generated were recorded by an infarometer which was mounted under the glass plate. Where metal slides over metal, these momentary Hash temperatures destroy the oxide layer on metals, resulting, because of their like molecular nature, in. a welding or bonding of the two metal surfaces. This results in metal exchange and wear. As hydrocarbon lubricants are destroyed at about 550017 some other substance in the oil is necessary to lubricate at these high temperature contact points. The Royal Society showed that the ideal substance to be added to the oil would be one that would be called to work at the same temperatures that destroy the hydro-carbon. This substance should be capable of providing a readily-deformable molecular lattice layer on metal surfaces and be capable of withstanding accelerating temperatures and pressures thereby preventing the welding. A number of substances were named by the Royal Society findings as having the ability to provide the lattice layer formation needed. But of all substances named in the findings, one was described as having the greatest all- round values. It was particularly effective in keeping Hash temperatures at lower values, thus preventing metal welding. The substance named is an integral part of the Bardahl formula. It is interesting to note that the additive oil Bardahl pioneered fifteen years ago introduced a theory of lubrication which only recently has been advanced and verified by leading lubrication scientists of the world as the best answer to modern friction and lubricating problems. Experiments performed by W. A. johnson, Chief Research Physicist of Skinner ik Sherman Inc., Boston, Mass., recently made the following experiments. He added 202 of Bardahl to a top quality heavy duty motor oil. He found. that the oil containing Bardahl lubricated up to 13OOOF. while the same oil alone completely failed at about 600OF. This corroborates the findings of the Royal Society and explains why hundreds of thousands of Canadian car and truck operators are obtaining much longer engine life, Bardahl is now the worldisl largest selling additive for oil and motor fuels in its field. The findings in the Royal Society report on lubrication are summarized in an illustrated booklet New Dimensionsv. We have a limited supply.
