Mengapa pa Cat Diper Diperluka lukan? n? Menga Ada dua alasan alasan utama untuk untuk mengecat : Untuk melindungi properti dan untuk alasan kosmetik Hal ini secara finansial sangat penting untuk melindungi struktur terhadap korosi. Sebuah sistem cat yang baik akan menjadi metode biaya-efektif untuk melindungi struktur: Umur struktur diperpanjang, biaya pemeliharaan berkurang dan resiko kecelakaan yang mempengaruhi orang-orang dan lingkungan berkurang .

Why do we paint? Safety and economy: The industry wishes to preserve their investments to avoid accidents. If it was cheaper to let constructions corrode, and simply build new ones when the safety limit was passed, we would have seen many more rusty plants, ships and platforms

Factors needed for corrosion To achieve corrosion we need a galvanic galvani c cell A galvanic cell consist of: • A Cathode : – The noble noble me metal tal / a alloy lloy (or part of metal) metal)
• An Anode: – The less less nob noble le meta metall / allo alloy y
• An electrical connection – between the two two metals, metals, conducting conducting electrical electrical current current (by electrons)
• An electrolyte: – Conductin Conducting g electrical electrical ccurre urrent nt (by iions) ons)

Galvanic Series The galvanic series is a table used to demonstrate the reactivity of different d ifferent metals When two metals are in contact with each other, the more reactive metal will corrode in preference to the less reactive metal Aluminum will therefore corrode in preference to iron when the two are connected The galvanic series is important when considering design with different materials Jotun Paint School

Corrosion Single piece of metal showing the anodic and catho cathodic dic sites. Corrosion occurs at the anodic sites. If the steel was all cathodic corrosion would stop. A piece of steel has thousands of anodic and catho cathodic dic sites. It is, however, unusual to find them uniform as various factors such as contaminants will cause different types of corrosion rates on a single piece of metal.
