Titanium is an important material having a high tensile strength-to-density ratio and high corrosion resistance. It has found applications in the aerospace, marine, automotive and biomedical industries. In some of the applications, it is important to have it as a highly liquid repellent, anti-icing and self-cleaning. There have been several attempts to make titanium superliquiphobic. The common pathways include chemical etching and anodizing. However, important characteristics such as self-cleaning, anti-icing and durability have not been investigated. If any durability data were reported, it was poor. In the current study, various superliquiphilic/phobic surfaces were fabricated using three pathways which include chemical etching, anodizing and nanoparticle-binder coating. Each surface was characterized for wettability, self-cleaning, anti-icing, self-cleaning properties and durability. This article is part of the theme issue ‘Bioinspired materials and surfaces for green science and technology’.

AbstractThis paper presents a high corrosion resistance Ni-graphene composite coating fabricated by co-electrodeposition on Cu substrate. First, GO was synthesized by improved Hummers’ method, and then different concentrations of GO aqueous solution were introduced to Ni Watt’s bath. During electrodeposition, GO and Ni ions were reduced simultaneously to form composite coating. The phase structure and morphology were covered by X-ray diffraction and scanning electron microscopy analysis, respectively. Atomic force microscopy (AFM) was employed to identify the surface topography of the coatings. Raman spectroscopy, Fourier transform infrared spectroscopy (FTIR), and electrochemical impedance spectroscopy (EIS) were used to study the synthesis of GO and its reduction during the plating process. Corrosion resistance of nanocomposite and that of pure Ni coating were compared by applying potentiodynamic polarization spectroscopy (PDS). The results showed that by increasing the amount of graphene oxide in solution, there has been a significant reduction in corrosion current density. As the EIS result showed, the high amount of GO reduction was obtained in GO concentration of 0.6 mg ml−1 and current density of 8 A dm−2. It is in a good agreement with data obtained from PDS. Analyses showed that the corrosion current density of corresponding coating was improved up to 0.2 μA cm−2, which means an improvement of about 100 times compared to pure Ni coating.

Sputter Deposited

Nanocrystalline, single bcc solid solutions of W-Mo alloys have been successfully prepared by D. C. magnetron sputtering in a wide composition. The corrosion behavior of the sputter-deposited W-Mo alloys was studied. The W-Mo alloys showed significantly high corrosion resistance in 12 M HCl at 30o C. Their corrosion rates are about one and half orders of magnitude lower than that of sputter-deposited tungsten and lower than that of the sputter-deposited molybdenum even after prolonged immersion.DOI: 10.3126/jncs.v21i0.217Journal of Nepal Chemical Society Vol.21 2006 pp.19-25
