Surface temperatures were measured by dynamic thermocouple technique. In dry friction the temperatures were in reasonable agreement with theory as proposed by Jaegar. When lubricants are used the behavior was very much a function of the lubricant. With some lubricants the temperatures can be obtained by extending the dry friction theory and assuming that the temperature rise observed is essentially due to the metal contact. When reaction films are involved, Rehbinder effect with the consequent reduction in plastic strength appears to be a possibility.
