Abstract

compared to the classical uncoated tools in a laboratory scale experiment in order to check the coating influence on process load, material flow and friction. The material flow, and consequently the friction, is investigated by means of visioplasticity techniques, by the insertion of marker rods in the deforming billet. AA6082 billets are deformed at typical extrusion conditions (520°C billet preheating, 5mm/sec ram speed) at three different extrusion ratios The deformed rods pattern of the butt is measured in order to analyze the friction effect. Finally, the test is repeated several times in order to monitor the rate of wear of the coated layers by means of optical microscopy measurements.
