DESIGN OF CORROSION PROTECTION TECHNOLOGY IN AN INDUSTRIAL ATMOSPHERE

U uvodu je dana definicija korozije, opisuju se razlozi nastanka, potencijalne posljedice i troškovi. Kasnije slijedi detaljnija klasifikacija korozijskih procesa uz primjere i fotografije s naglaskom na ekonomskom značaju korozije. Potom se piše o konstrukcijskim čelicima, njihovim mehaničkim i korozijskim svojstvima. Slijedi analiza korozijskih sredina prema agresivnosti s detaljnijim opisom industrijske i morske atmosfere koje se smatraju najagresivnijim korozijskim sredinama. Potom se detaljno opisuju tehnologije površinske zaštite s naglaskom na zaštitu prevlačenjem. Pri analizi prevlačenja, dolazi se do zaključka da su najbolji sustavi zaštite oni s višeslojnim prevlakama. Slijedi opis projektiranja tehnologije površinske zaštite, koje elemente obuhvaća i kako ga je potrebno provesti. Nakon toga u eksperimentalnom dijelu, dan je prikaz projektiranja površinske zaštite mosta u primorskim uvjetima. Eksperimentalni dio obuhvaća snimanje postojećeg stanja, razradu tehnologije, nanošenje premaza i ekološko zbrinjavanje otpada. Sve je potkrijepljeno slikama s terena prilikom izvođenja radova te slikama opreme koja se koristi pri kontroli premaza. Na kraju slijedi zaključak s vlastitom analizom.The introduction part starts with corrosion definitions, explains the reasons for the occurence, potential ramifications and costs. Later follows a more detailed classification of corrosion processes with examples and photographs. Emphasis is put on the economic importance of corrosion. After that, it is written about construction steels, their mechanical and corrosive properties. There is a corrosive environment analysis classified on the degree of agresiveness. More detailed description is given about industrial and sea atmosphere which are considered to be the most aggresive ones. Subsequently, surface protection tecnology is described in detail, with emphasis on coating protection. In the coating analysis, it is concluded that the best systems of protection are those with multilayer coatings. Furthermore, there is a description of the design of surface protection technology, which elements it covers and how it should be carried out. In the experimental section, the design of the surface protection of the bridge in coastal conditions is shown. The experimental part includes recordings of the existing state, technology development, coating application, and ecological waste disposal. Everything is backed up by terrain photographies when performing the work and photographies of equipment used for coating control. Finally, there is a conclusion with own analysis
