             abstract = "There has been a recent increase in both the production and 
                         consumption of ethanol due to the numerous environmental 
                         advantages that it offers, such as the fact that it can be 
                         produced from a variety of renewable materials, for instance corn 
                         and cellulose, or it can be obtained from sugarcane bagasse and 
                         biomass (2nd and 3rd generation ethanol). The result of this is 
                         that nowadays ethanol is widely seen as the dominant biofuel or as 
                         a blend component in gasoline or pure fuel - in many countries. 
                         However, one disadvantage of the use of ethanol is the high 
                         corrosive behavior that occurs when its hygroscopic properties are 
                         exposed to a large number of materials. Xiaoyuan Lou and Preet 
                         Singh showed that the increase of water concentration in ethanol 
                         induces pitting and metal loss. Diamond-Like Carbon (DLC) films 
                         may be a solution to this problem due to the fact that they can be 
                         deposited inside tubes, offer good protection levels against 
                         corrosion, and reduce the friction coefficient and wear. This 
                         paper shows the tribocorrosion and corrosion studies of DLC films 
                         deposited on stainless steel grade 304 (SS304) substrates in order 
                         to gauge its appropriateness usage in the construction of 
                         pipelines and fuel storage tanks. The surface morphology was 
                         analyzed before and after 14 days of immersion. The 
                         tribocorrosion, friction coefficient, and wear rate were studied 
                         in ethanol to see the effects of water concentration. The films 
                         showed good adherence to the substrates. Corrosion and 
                         tribocorrosion results showed that for bare Stainless Steel 304 
                         the increase of the water content increases the corrosion and the 
                         friction coefficient. DLC coated samples presented few points of 
                         delamination, and the friction coefficient and open circuit 
                         potentials were very low compared with the bare sample which was 
                         water concentration independent.",
