Abstract
Cilj ovog rada je istražiti proces korozije i nastanka patine u umjetnoj kišnici. Istraživanje je provedeno na bakru, te tri njegove legure (PbCu, CuSn6 te CuSn12). Metalni uzorci izloženi su djelovanju blago kisele i neutralne otopine umjetne kiše kroz dva tjedna nakon čega su karakterizirana svojstva patiniranih uzoraka. Mjerenja su se provodila elektrokemijskim metodama s istosmjernom (DC) i izmjeničnom (AC) strujom kako bi istražili korozijska svojstava svakog od ispitivanih metala. Dobiveni rezultati pokazuju različito ponašanje svakog od metala u oba ispitivana medija. Iako je izlaganje uzoraka otopinama umjetne kiše trajalo 21 dan, kod većine uzoraka uočava se promjena korozijskih parametara u vremenu što govori da je površina uzoraka još uvijek vrlo reaktivna.
Abstract (english)
The goal of this research is to explore the process of corrosion and forming of patina in artificial rainwater. The research was conducted on copper and three of its alloys (PbCu, CuSn6 te CuSn12). Metal samples were exposed to mildly acidic and neutral solution of artificial rainwater for two weeks, after which the properties of patinated samples were characterized. The measurements were conducted by electrochemical methods with direct (DC) and alternating current (AC), in order to find out as much corrosion properties as possible. The given results show us a different behavior of each metal in both of the used mediums, which gives us, chemical engineers, an opportunity to adjust the usage of every individual metal depending on the work conditions, quality requests and finally, long term cost-effectiveness.
