Experimental studies of the Cu-Sb-Sn and Ni-Sb-Sn systems have been carried out by the wetting tests, followed by the analysis of the microstructural evolution occurring at the interface between the liquid alloy and solid substrate. The wetting experiments on the Sb30Sn70 / (Cu, Ni) and Sb38.4 Sn61.6 / (Cu, Ni) systems have been performed by...

In this work, a photospectrometric method was used to quantify chromium evaporation from the AISI 441 ferritic stainless steel. Experiments were conducted for 250 h in the temperature range of 650–850 °C to evaluate the time and temperature dependence of chromium evaporation in the initial oxidation stage. The results showed a thermally...

This review represents the state of the art in the thermophysical properties of liquid Ag-Sn alloys highlighting the surface and wetting properties of Ag-Sn eutectic solder. It includes an atomistic approach developed within the framework of statistical mechanical theory in conjunction with a Quasi Lattice Theory that, through a rigorous...

The Sm–Ni–Al phase relationships at 800 °C have been investigated by using several well–focused experimental techniques such as X–Ray Powder Diffraction (XRPD), Light Optical Microscopy (LOM) and Scanning Electron Microscopy (SEM) coupled with Energy Dispersive Microprobe Analysis (EPMA). The isothermal section of the Sm–Ni–Al system at 800 °C...

To properly design and optimize liquid-assisted processes, such as reactive infiltration for fabricating lightweight and corrosion resistant SiC/TiSi2 composites, the extensive knowledge about the interfacial phenomena taking place when liquid Si-rich Si-Ti alloys are in contact with glassy carbon (GC) is of primary importance. To this end, the...

Although aluminium alloys are known to exhibit generally good corrosion resistance in natural seawater, they may encounter generalised and localised corrosion phenomena. In this work, an aluminium alloy casted referring to the AA 5083 composition was tested in artificial vs. natural seawater exposed to the photoperiod. SS 254 SMO samples were...

Commercial brass OT60 is commonly used for food processing. The inhibition of its dezincification in presence of the biofilm forming Pseudomonas fluorescens was documented in this work. Electrochemical polarizations, Electrochemical Impedance Spectroscopy and post treatment analyses were carried out during 120 h of immersion in presence of...
