“…Suitable procedures and materials are needed to hinder the degradation and to convert corrosion products to stable and inert phases; these materials include the 'corrosion inhibitors'. [5][6][7] Their production needs extended study of all the complex parameters that cause degradation. This includes chemical composition and microchemical structure of the artifact, chemical reactions, chemical and structural nature of corrosion products, and also the burial context features such as local pH and electrical resistivity of soil, water flow through ground layers, and humidity.…”

Investigation of the chemical composition, surface structure, metallurgical features, corrosion mechanism, and surface modification techniques of archeological metallic artifacts from Romans and pre-Roman times aimed to simulate the most commonly used Cu-based and Ag-based alloys. These simulated reference alloys will be used as sacrificial materials to study the most appropriate conservation materials and procedures. In the present work, laser-induced breakdown spectroscopy (LIBS) is introduced as a new validated surface mapping technique to study the micro-chemical distribution of elements in binary reference copper-silver alloy samples. Using different techniques for surface and bulk analysis, such as SEM coupled with energy-dispersive X-ray spectroscopy and X-ray diffraction, it has been proven that LIBS is a simple, sensitive, and direct technique in the determination of heterogeneity of the sample's surface. By changing the laser wavelength (λ/nm) and focal length of the used focusing lens (f/cm), different spot sizes can be obtained. It was possible to control the spatial resolution in mapping the investigated samples' surface and to achieve local chemical information. In the present work, Q-switched neodymium-doped yttrium aluminum garnet laser has been used at its fundamental wavelength 1064 nm and its second harmonic 532 nm. The studied samples were specially manufactured heterogeneous copper-silver alloys with known grain size as studied via SEM investigation. The obtained LIBS results are in good agreement with those by other analytical techniques and extend the applicability of the surface techniques to study metallic ancient objects.

“…Corrosion may not have a deleterious effect on a material immediately but it affects its mechanical strength, physical appearance and it may lead to serious operational problems in future, [7]. Corrosion attack on Al surfaces is usually quite obvious since the products of corrosion are white and generally more voluminous than the original base metal, [8] .It is evident as general etching, pitting, or roughness of the Al surfaces [9]. In acidic media, i.e.…”

The paper presents the effect of vanadium addition to aluminum and aluminum grain refined by titanium on the micron level, in the range from 0.005 wt % to 0.236 wt %, on their corrosion resistance in acidic solution, HCl, at three different temperatures namely: 25 °C, 40 °C and 60 °C. It was found that the corrosion rate was slightly increased by the addition of any percentage of vanadium at 25 °C. Furthermore, it was found that the corrosion rate increased with the increase of temperature at any percentage of vanadium addition in the case of both aluminum and aluminum grain refined by titanium. However it was found that addition of vanadium at any percentage to either aluminum or aluminum+ titanium, resulted in decrease of the corrosion rate i.e. improvement in their corrosion resistance in acidic solution at 40 °C and 60 °C. The maximum achieved reduction in corrosion rate was 77 % at 40 °C and 0.148 wt % vanadium addition.
