Friction and Wear Behaviors of Textured Metal Surfaces by Vibration-assisted Microcutting in Dry Sliding

抄録

A surface texturing method using the vibration-assisted microcutting was developed. In such a process, a triangular pyramidal diamond indenter is oscillated in the cutting depth direction with an amplitude of several tens of μm using a fast-tool-servo system. The burrs or pileups generated around each dimple like pattern after texturing can be removed on-machine by just supplementary conducting the conventional microcutting. In this report, c2680 brass plate surfaces were successfully textured with a few different kind of textured area densities using the developed method. Their dry sliding friction and wear characteristics were examined using the ball-on-plate sliding tests. As a result, it was clarified that both the coefficient of friction and wear were decreased with increasing the textured area density.
