Today a major environmental problem is global warming that is mainly caused due to exhaust and emission of gases. The only way to reduce their ill-effect is by improvement in fuel efficiency of I.C. engines, where most of the power is lost to overcome the friction. In this work, nanoporous anodized layer is formed on an aluminium substrate surface by anodization. Anodization was carried out at different parameters such as voltage, temperature, time to find out optimum conditions to obtain well ordered nanoporous layer. Characreization of anodized porous layer was done by FE-SEM and EDS. After synthesis, anodized layer was treated with anionic surfactant and dipped in lubricant (SAE-15) for tribological applications. Tribology testing was performed on lubricated anodized surface which shows better results in wear and friction as compared to bare substrate. This technique has a lot of potential in improving fuel consumption of I.C. engines, thus may go a long way towards our goal to save environment.
