| Summary: | Wear resistance is one of the critical mechanical properties for materials
which accept constant friction, such as gears and ball bearings. Those materials
are expected to have a good wear resistant property. One of the techniques used
in enhancing wear resistant of a material is increasing the material’s hardness.
On this research, wear tests are conducted on several aluminum alloys
which have been given treatments, such as alloying, heat treatment, and surface
treatment using pin on disk method. The experiment is performed by the same
load, rotating speed, and duration on each material, which results in material’s
wear loss. The wear resistance value is determined by the value of mass loss.
The experiment's result shows that an increased value of aluminum's
hardness corresponds to a raise in wear resistance value, which is represented
by a decrease in mass loss. Aluminum 2024, with artificial aging process at
190? for 7 hours, has a better wear resistance property than Aluminum 2024
super saturated solid solution. The artificial aging process introduces
precipitates which enhance the aluminum's hardness.
