20.500.12556/RUL-116895 Anodni materiali za aktivno protikorozijsko zaščito Anode materials for active corosion protection Diplomska naloga je posvečena reševanju problema korozije kovin v industriji. S pravim pristopom in znano tehnologijo pa se s to problematiko lahko uspešno soočimo in jo omejimo, ter pripomoremo k večji ekonomičnosti in zanesljivosti kovinskih struktur. Po podatkih iz študije »Mednarodni ukrepi za preprečevanje korozije« (ang. International Measures of Prevention, Application and Economics of Corrosion Technology - IMPACT), izvedene s strani organizacije iz Združenih držav Amerike za nadzor korozije NACE (ang. National Association of Corrosion Engineers), korozija kovin v industriji na svetovni ravni letno povzroči za 2,5 trilijonov dolarjev škode, kar predstavlja 3,4% globalnega bruto domačega proizvoda. V isti študiji ugotavljajo, da bi s pravim pristopom, z današnjo tehnologijo, lahko letno privarčevali 15-35% na račun protikorozijskih sistemov [1]. V uvodnem delu smo opisali termodinamiko korozijskega procesa, pogoje za nastanek korozije, ter pojasnili elektrokemično ozadje poteka korozije. V nadaljevanju smo izvedli laboratorijske preizkuse in sicer smo se omejili na galvansko povezavo dveh kovin v prevodnem elektrolitu. Opisali smo teorijo preprečevanja oziroma omejevanja poteka korozije, ki posega v elektrokemični del korozijskega postopka. Z uporabljenimi kriteriji, matematičnimi izračuni in merilnimi metodami smo dokazali učinkovitost elektrokemičnega preprečevanja korozije. This thesis is dedicated to solving corrosion problem in the industry. With the right approach and known technology, we can succsesfully limit the effects of this natural occurance and therefore contribute to greater efficiency and safety of industrial metal structures. Based on the information from the study: International Measures of Prevention, Aplication and Economics of Corrosion Technology – IMPACT, made by the National Association of Corrosion Engineers, the cost of corrosion in the industry is estimated to be 2.5 trillion dollars, which is equivalent to 3,4% of the globat Gross Domestic Product (GDP). In the same study it is estimated that by using available corrosion control practices, it is suggested that savings of between 15-35% of the cost of corrosion could be realized [1]. In the preface we described the thermodynamic and electrochemical process of corrosion. Than we made laboratory tests with galvanic connections of two dissimilar metals in the electrolyte showing the corrosion processes. We described the theory of corrosion prevention, that takes place in the electrochemical part of corrosion process. With the known criterias, mathematical calculations and measurement techniques, we proved the effectivnes of electrochemical corrosion prevention. korozija korozijska celica protikorozijska zaščita katodna zaščita corrosion corrosion cell corrosion protection cathodic protection true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2020-06-15 14:55:14 2020-06-15 14:55:20 2022-08-29 03:39:47 0000-00-00 00:00:00 2020 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 50261 Erculj_Ziga_-_Anodni_materiali_za_aktivno_protikorozijsko_zascito.pdf Erculj_Ziga_-_Anodni_materiali_za_aktivno_protikorozijsko_zascito.pdf 1 0B99A69799E4307C90F95528D5F7223B 1ad2a937454421b39c3a367d7414fb1cbc342724f16d250a57fb7e2ce62ff3c1 0900a1d5-a1b9-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=130598 Fakulteta za elektrotehniko 0 0 0
