Its appearance differs considerably from the original as a result of corrosion. The strong interaction between atmospheric pollutants and the bronze alloy in Ljubljana city centre has resulted in the formation of a secondary patina. With the aim to determine the corrosion state of the Prešeren monument and to ensure the data for the next restoration procedure, a chemical and physical examination was performed. The composition of the patina was analysed using energy-dispersive spectroscopy coupled with scanning electron microscopy and anon-destructive method for determining the alloy composition was used. The different types of patina were studiedSpomenik v spomin pesniku Francetu Prešernu v Ljubljani je bil odkrit l. 1905, renoviran pa l. 1970. Danes je njegov zunanji videz zaradi bolezni brona precej drugačen od tistega ob postavitvi. Največji razlog za to je onesnaženje okolja v centru Ljubljane. Da bi ugotovili korozijsko stanje Prešernovega spomenika in pridobili potrebne podatke za predvidene restavratorske posege, smo izvedli kemijske in fizikalne analize brona spomenika. Sestavo patin smo analizirali z energijsko disperzijsko spektroskopijo rentgenskih žarkov, kemijsko sestavo brona pa z nedestruktivno metodoTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
