Friction, wear and the role of additives in their control, the area of the sliding surface. These laws are attributable to Leonardo da Vinci and they were then rediscovered by Amontons in 1699. Coulomb, in 1781, distinguished between static friction, the force required to start sliding, and kinetic friction, the force required to maintain it. He showed tha

Book 19972nd editiong complexity. The impetus for lubricant development has arisen from need, so lubricating practice has preceded an understanding of the scientific principles. This is not surprising as the scientific basis of the technology is, by nature, highly complex and interdisciplinary. However, we believe that

Fabrizio Colombo,Jonathan Gantneron are created by the addition of special EP additives. The base fluid also functions as the carrier for these additives and must therefore be able to keep the additives in solution under all normal working conditions.
