The decreasing of friction properties of aluminium from anodizing process and silicon dioxide supplement

Abstract

Aluminum is a lightweight material which are popularly used in various parts of the industry. However, there are some limitations on the tribological properties such as abrasive wear and friction when it was compared to other metals. Tribological properties of aluminium was improved with anodizing process and silicon dioxide supplement. the effect of time on surface structure and friction coefficient were studied with with scanning electron microscope and sliding wear tester. It was found that friction coefficient of aluminium was decreased after improvement process was applied.
