Monitoring of the corrosion state inside these historical brass instruments before and after being played is essential to check the efficiency of preventive conservation protocols. As corrosion of metal artifacts is an electrochemical process, electrochemical techniques are the method of choice, especially since nowadays these measurements can be carried out in situ and are non destructive.&nbsp;In order to interpret the \u201cin situ\u201d electrochemical measurements \u201cex situ\u201d surface analytical methods such as XPS and XAES (X-ray excited Auger spectrospcopy) performed on brass surfaces in well defined conditions (after controlled exposure to known solutions) are essential.&nbsp;The influence of saliva composition has been studied. <\/p>\n\n\n\n<div class=\"wp-block-media-text is-stacked-on-mobile\" style=\"grid-template-columns:54% auto\"><figure class=\"wp-block-media-text__media\"><img loading=\"lazy\" decoding=\"async\" width=\"705\" height=\"309\" src=\"https:\/\/sites.unica.it\/superfici\/files\/2025\/08\/Graph_Brass_alloys.jpg\" alt=\"\" class=\"wp-image-102 size-full\" srcset=\"https:\/\/sites.unica.it\/superfici\/files\/2025\/08\/Graph_Brass_alloys.jpg 705w, https:\/\/sites.unica.it\/superfici\/files\/2025\/08\/Graph_Brass_alloys-300x131.jpg 300w\" sizes=\"auto, (max-width: 705px) 100vw, 705px\" \/><\/figure><div class=\"wp-block-media-text__content\">\n<p>Surface analytical strategy by X-AES to identify the chemical state in copper and zinc <a href=\"https:\/\/sites.unica.it\/superfici\/x-aes-of-copper-and-zinc\/\">&gt;&gt;&gt;<\/a><\/p>\n\n\n\n<p>Electrochemical sensor to measure corrosion rate inside the tuning slides <a href=\"https:\/\/sites.unica.it\/superfici\/electrochemical-sensor\/\">&gt;&gt;&gt;<\/a><\/p>\n\n\n\n<p>Ageing of brass alloys in model electrolytes and in artificial saliva <a href=\"https:\/\/sites.unica.it\/superfici\/ageing-of-brass-alloys\/\">&gt;&gt;&gt;<\/a><\/p>\n\n\n\n<p>Influence of saliva composition on corrosion of brass alloys <a href=\"https:\/\/sites.unica.it\/superfici\/influence-of-saliva-composition\/\">&gt;&gt;&gt;<\/a><\/p>\n<\/div><\/div>\n\n\n\n<p><strong>Publications:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>F.
