THE EFFECT OF HEAT TREATMENT AND SURFACE ANODIZATION ON FRICTION AND WEAR COEFFICIENT OF ALUMINIUM 2024 USING PIN ON DISK METHOD

The use of aluminum alloys as a material for engineering components that rub against each other is increasing, so it important to know the friction characteristics these alloys. In this study, Aluminum 2024 was given heat treatment with variation in aging time and anodization. Then, wear coefficient tests were carried out using pin tool on disc. effect surface anodization are determine amount test when rubs made AISI 52100 Steel. by adding lubrication parameter. results showed had better resistance than which not treated. This because creates precipitates can increase aluminum's hardness resistance. Whereas anodized specimens, alumina layer act an abrasive grain high enough load continuously, testing mode changes from dry sliding three body decreased From results, affects alloy, leads value friction. harder sample surface, smaller obtained. Furthermore, applying lubricant will also decrease sample. Lubricating oil provide more significant reduction air. Finally, anodizing reservoir occurs.
