Surface modification of titanium implants is recently considered by several researchers. In this study, PEO was performed over commercially Ti-6Al-4V alloy pellets in an aqueous electrolyte containing calcium acetate (C.A.) and calcium glycerphosphate (Ca-GP) with a Ca/P molar ratio of 6.8, and applying current density of 0.212 A/cm2, frequency of 100 Hz and duty ratio of 60% for 4 min. In the next step, hydrothermal treatments were carried out for various durations and at different temperatures inside an autoclave chamber containing a NaOH solution with pH of 11.5. XRD and SEM results confirmed formation of needle-shaped HAp after all hydrothermal conditions. Maximum intensity of HAp peaks was observed for the hydrothermally treated sample at 190 °C for 15 h. Moreover, crystallinity degree of HAp was increased by increasing hydrothermal duration and temperature. According to the SEM line scan analysis of cross section of the PEO coated sample after hydrothermal treatment at 190 °C for 15 h, it seems that Ca+2 and [PO4]-3 ions from internal layer of amorphous coating diffuse to the coating surface and dissolve into the solution during hydrothermal treatment, and finally precipitate on the outer layer of coating as needle-shaped HAp. © 2012 Elsevier Ltd and Techna Group S.r.l.

The aim of this investigation was the surface functionalization of industrial ceramic tiles by soluble salts addition to improve mechanical properties (resistance to scratch and wear) preserving the aesthetical aspect of the final product. This objective was pursued through the application of different solution of zirconium capable to be transformed in zirconia nanoparticles during the material sintering. The solutions, in different concentrations, were deposited (300 g/m2) on unglazed green tiles by air-brushing. The obtained products were polished and characterized in terms of microstructure, surface micromechanical and technological properties based on the UNI EN ISO reference rules. The final aesthetical aspect of the products and the obtained hue variation were evaluated by means of UV-vis spectroscopy and colorimetric analysis. © 2009 Elsevier Ltd. All rights reserved.

The aim of this study was to assess surface functionalization of industrial ceramic tiles through the addition of soluble salts to improve mechanical properties (scratch and wear resistance) and conductivity, while preserving the aesthetic aspects of the finished product. This objective was pursued through the application of different solutions of titanium and silver with a potential for transformation into titania and silver nanoparticles during the sintering of the material. The solutions, in different concentrations, were applied (300g/m2) to unglazed green tiles by air brushing. The resulting products were polished and characterized in terms of microstructural, surface micromechanical, and technological properties based on the UNI EN ISO reference standards. The electrical conductivity deriving from the presence of titania and silver was also established with specific tests. The results were found to correlate with the results obtained from the addition of zirconium solutions as reported in part I of the paper. © 2010.

The ECO-INK project proposes a green, innovative and comprehensive solution to the great limitations of the digital printing technology within the ceramics decoration sector. The main objectives of the project are to explore new market opportunities and boost the competitiveness of METCO srl business, while addressing EU/global challenges on Climate Change and following the indications of the Stockholm Convention on persistent organic pollutants & the Stimulating technologies for sustainable development: an environmental technologies action plan for the European Union: ECO-INK will promote environmentally-friendly activities as well as guarantee the safe elimination of substances, harmful to human health and the environment, as well as the reductions in their production and use, through the substitution of current solvent based ink with water based inks (WSI) for ceramic tile production. for METCO itself, with the introduction of WSI in their production chain, there will be a saving of about 240-360t of solvent each year, corresponding to save about 0,5-1M if the solvent substituted is naphtha and approximately 7281,093t of CO2 emissions per year. Considering the global market the expected figure is very impressive, since itll be possible to save 620,000t CO2 emission per year. METCO srl foresees a 2-years investment (about 1.8M) to complete the optimization of WSI and to setup the whole technological package. METCO then envisages a full production and commercialization of 450-1.350-2.700t ECOINK ecoformulations per Years 3-4-5. This is expected to result in a \487% ROI by 2019 and in a METCO srl growth with \45 human resources by 2021.
