             abstract = "The ceramic and carbon coatings such as titanium nitride (TiN) and 
                         diamond-like carbon (DLC) coatings are characterised by good 
                         mechanical properties and chemical inertia. The objective of this 
                         work is to compare the wear, friction, adhesion and corrosion 
                         behaviour of commercial TiN and DLC coatings deposited on AISI 420 
                         stainless steel, by plasma-assisted techniques. The microstructure 
                         of the coatings was characterised by optical and electronic 
                         microscopy and X-ray diffraction. The hardness and Youngs modulus 
                         were measured by nanoindentation. Pin-on-disk, fretting and 
                         abrasive wear tests were performed. Adhesion was evaluated by 
                         means of Scratch Test and Rockwell C Indentation. The corrosion 
                         behaviour was evaluated by Salt Spray Fog and electrochemical 
                         tests in chloride solutions. The thickness of both coatings was 
                         between 1 and 1.5 µm. The hardness was 26 GPa and 34 GPa for DLC 
                         and TiN coating, respectively. The results showed that the TiN 
                         coatings presented better abrasive wear resistance than the DLC 
                         coatings; however, the latter was more resistant to the pinon-disk 
                         test, fretting and it had a lower friction coefficient. Both 
                         coatings showed far better wear resistance than the untreated 
                         steel. Finally, TiN coatings had better adhesion to the substrate 
                         than DLC coatings, proved in both tests. Regarding the corrosion 
                         behaviour, both coatings exhibited acceptable corrosion resistance 
                         in the Salt Spray Fog Test, but only the DLC coatings had both 
                         nobler corrosion potential and higher breakdown potential than the 
                         TiN coatings in electrochemical tests.",
