h i g h l i g h t s ZrO 0.8 N 0.2 coatings were deposited by DC sputtering using air as the reactive gas. The ZrO 0.8 N 0.2 films grew in the cubic phase and preferentially oriented in plane (222). A thin film of ZrO 2 (c) promotes the growth of ZrO 0.8 N 0.2 . The coating of ZrO 2 /ZrO 0.8 N 0.2 increases the corrosion resistance of steel. a b s t...

Titanium alloys present excellent mechanical and corrosion properties, being widely employed in different industries such as medical, aerospace, automotive, petrochemical, nuclear and power generation, etc. Ti6Al4V is the α-β alloy most employed in industry. The modification of its properties can be achieved with convectional heat treatments and/o...

Ti6Al4V is the α-β alloy most employed in industry. The modification of its properties can be achieved with conventional heat treatments and/or with laser processing. Laser remelting (LR) has been applied to Ti6Al4V by other authors with excimer and Nd-YAG laser, employing pure argon as shielding gas to prevent risk of oxidation. In the present con...

Ordered porous alumina layers prepared by two-step anodising in phosphoric, oxalic and sulphuric acids have been characterized at sub-nanometer scale using electron microscopy techniques. FEG-SEM and STEM-HAADF images allowed estimating the pore size, cell wall and pore wall thicknesses of the layers. Nanoanalytical characterization has been perfor...
