Moly and the Earth?
When thinking of the surface of metal, bearings have peaks and valleys. An example is the earth. If a ball bearing were enlarged to the size of the earth, its surface would look like that of the earth. In terms of lubrication the tops of the mountains are called asperities. Friction takes place when the “mountain tops” of one surface come into contact with the mountain tops of the other surface to the extent that causes a small to large “top” of the mountain to break away. At the microscopic level of asperities, the tops of the two opposing mountain tops weld together more or less, depending on pressures and other factors, and then break apart. The breaking apart creates friction. Once apart, wear has taken place, not to mention the existence of microscopic particles freely moving about in the grease or oil to act as an abrasive. Because of the physical nature of moly it fills in the valleys and covers the peaks, plating out, to prevent metal-to-metal contact or to minimize it. The ben
