| Abstract Scope |
Equal channel angular pressing is a severe plastic deformation process used to refine the grain structure of metals and alloys. Aluminium and its alloys are suitable for this process because ultra-fine grain structurescan produced for these materials.
In the present study, commercially pure aluminium was processed by ECAP to improve its tribological properties. Wear loss and coefficient of friction were evaluated. An attempt was made to optimize the process parameters in order to get better wear and friction properties using Design of Experiments developed by Taguchi.
The wear loss was reduced after each passofcommercially pure aluminium, significantly in pass one. There was a significant reduction in coefficient of friction after pass one and pass two. Out of all input parameters that were taken into consideration in respect of COF and wear loss, the speed of the disc had the greatest influence, followed by the applied load. |
