LEAD-FREE COPPER- BASE ALLOYS FOR FRICTION COMPONENTS: SINTERABILITY AND RECRYSTALLIZATION

摘要

Engine parts subjected to high loads and relative movement undergo heating and energy losses due to friction that can lead to overload, loss of material, or fatigue. The use of friction bearings, placed between the connecting rod and the crankshaft, avoids these problems and offers enhanced wear resistance and friction behavior; this allows the system to operate under high loads and a high relative velocity if the different parts are lubricated,
