Ovim diplomskim radom obuhvaćena je tehnologija obrade i pripreme površine elektroforezom, pri čemu su prethodno opisane klasifikacije procesa korozije kako bi se dobio uvid i odgovor na pitanje zašto je ovaj postupak zaštite strojeva izuzetno bitan. Tehnologijom zaštite metala opisani su neki od postupaka kojima se vrši zaštita različitih tipova konstrukcija koje susrećemo svakodnevno, a svojom neadekvatnom zaštitom mogu prouzročiti otkazivanje pojedinih dijelova sustava kako i čitavih postrojenja koji za posljedicu mogu imati znatne ekonomske gubitke. Provedenom analizom željelo se ukazati na radnu okolinu u kojima se nalaze poljoprivredni strojevi jer je ista vrlo specifična i pogodna za nastanak različitih tipova korozije zato što su većinom svi dijelovi strojeva izrađeni od metalnih dijelova koji kako je poznatu su vrlo podložni nastanku korozije. Procesom elektroforeze detaljno se pristupilo uvidu u sam postupak pri čemu nam je tvrtka Same Deutz-fahr Žetelice izašla u susret i omogućila da određenu poziciju popratimo kroz cijeli postupak predtretiranja u zato predviđenih 11 kada, nakon kojih vršimo postupak bojanja i potom ispiranje u dodatne dvije kada. Poslije završetka samog postupka vrši se kontrola uzoraka koji su obrađeni ovim procesom kako bi se ustanovila njihova ispravnost i osigurala visoka kvaliteta konačnog proizvoda.

This graduate thesis encompasses technology for processing and preparation of electrophoresis surfaces, in which the classification of the corrosion process was described in order to gain insight and to find an answer to why the process of machine protection is extremely important. Metal protection technology is described by some of the procedures used to protect the various types of constructions we encounter on a daily basis, and by their inadequate protection, they can cause failures in certain parts of the system as well as failures of entire installations which can result in significant economic losses. The analysis was intended to point to the working environment in which agricultural machines are placed because it is very specific and suitable for the appearance of different types of corrosion and also because most of the machine parts are made of metal which is known to be very susceptible to corrosion. The process of electrophoresis was observed in detail during the procedure itself, whereby thanks to Same Deutz-fahr Žetelice company we were able to follow a certain position throughout the pre-treatment process in 11 designated tubs, after which we performed the coloring and flushing procedure in two additional tubs. After the completion of the procedure, quality control is carried out on the samples in order to establish their correctness and ensure high quality of the finished product.
