Abstract
Purpose
The purpose of this paper is to increase wear resistance of aluminum.
Design/methodology/approach
The authors have studied the ways to improve the tribological performance of aluminum by assembling stearic acid on aluminum coated by sol-gel-derived TiO2 film. The samples were characterized by infrared spectroscopy, contact angle measurements and a macro friction and wear tester.
Findings
Enhanced wear resistance was clearly obtained after functionalization of TiO2 film on aluminum by stearic acid.
Originality/value
The relevant results might be helpful for guiding the surface modification of aluminum devices in industrial applications.
