Impressed current cathodic protection systems are used in combination with organic coatings to prevent corrosion of hulls. The reaction species which are formed in the proximity of the anodes, like chlorinated compounds and acidity, can stress the antifouling paints of the protective coating system. A 3 x 3 matrix was defined to drive the tests...

Although Aluminium alloys are known to exhibit generally good corrosion resistance in natural seawater, they may encounter generalized and localized corrosion phenomena. In this work, an Aluminium alloy casted ad hoc referring to the AA 5083 composition was tested in artificial vs. natural seawater exposed to the photoperiod. OCP and SEM data...

This Special Issue in honor of Prof. Fabio Casciati and Prof. Lucia Faravelli, both retired Professors from the University of Pavia (Italy), proposes papers in the spirit of their activity, with a strong scientific interaction between researchers from different backgrounds, operating in the fields of Applied and Computational Mechanics by...

In the framework of joining processes of Ultra High Temperature Ceramics (UHTCs), sessile drop experiments were performed in the Ni-B/ZrB2 system in the range 1110°≤T≤1200°C. They show that, at temperatures between 1110 and 1150°C, isothermal solid-liquid transitions occur in a sequence; while in fact at T≥1200°C the drop melts without any...

Abstract An investigation of melting equilibria in the Ni-rich part of the Bsingle bondNisingle bondZr system was carried out by means of a combined experimental and computational approach, in order to improve the interpretation of wetting experiments of Bsingle bondNi alloys on ZrB2 substrates. Several samples along the Nisingle bondZrB2...

Metal-ceramic joints represent an important choice for biomedical devices, in orthopaedic field or as micro-stimulators. ZrO2-Ag-HEA joint is here proposed to replace the currently used Ti6Al4V by new Ti-based refractory HEAs. To evaluate the system reactivity, wettability of ZrO2 by different Ag-based alloys at 1000 degrees C and their...
