| Summary: | For components that often receive friction, wear resistance is an important
mechanical property. In order to increase its wear resistance Al-Cu-Mg alloys is
processed with heat treatment and surface treatment. The wear characteristics of
aluminum alloys that are treated with heat treatment and anodized are rarely carried
out.
On this research, wear testing, which uses a pin on a disk method, is done to
aluminum 2024. The test variation parameter is the hardness of the material that
has been given various heat treatment and anodized. The test is performed with the
same loading, speed and duration of testing. The hardness value is obtained from
rockwell hardness test and the wear resistance value is obtained from the mass loss
of each test material.
The results of the test shows that aluminum material which has been given
heat treatment has better resistance than that of which is not given heat treatment.
This is due to the heat treatment creates precipitates which can increase the
hardness and wear resistance of the aluminum. Whereas for anodized specimens,
the alumina layer when given a high enough friction and load continuously can act
as an abrasive grain so the wear testing mode changes from dry sliding wear to
three body abrasive wear that effect decreased wear resistance. |
