             abstract = "Diamond-like carbon (DLC) films have been use in numerous 
                         industrial applications due to its mechanical properties such as 
                         low friction coefficient, high hardness, and high adherence on 
                         different substrate materials. It has been demonstrated that the 
                         DLC surface can be modified with oxygen plasma treatment. The 
                         purpose of this paper is to study two kinds of surface treatments 
                         (atmospheric and low pressures) using oxygen gas for different 
                         etching exposure times in DLC films. Plasma durability along the 
                         time was also evaluated. DLC films were deposited using plasma 
                         enhanced chemical vapor deposition technique. The properties of 
                         DLC treated for both techniques in different exposure times were 
                         investigated through Raman, AFM and contact angle measurements. D 
                         band position slightly shifts toward lower wave numbers after 
                         oxygen plasma etching treatment whilst the surface becomes 
                         rougher, although the roughness values are still lower. A 
                         conventional wetting contact angle method was used to study the 
                         surface properties of DLC films with different treatments. The 
                         wetting contact angle reduced significantly due to the increase of 
                         carbonoxygen sites on the surface.",
