Besi ditemukan digunakan pertama kali pada sekitar 1500 SM. Tahun 1100 SM, Bangsa hittites yang merahasiakan pembuatan tersebut selama 400 tahun dikuasai oleh bangsa asia barat, pada tahun tersebut proses peleburan besi mulai diketahui secara luas. Tahun 1000 SM, bangsa yunani, mesir, jews, roma, carhaginians dan asiria juga mempelajari peleburan dan menggunakan besi dalam kehidupannya. Tahun 800 SM, India berhasil membuat besi setelah di invansi oleh bangsa arya. Bijih besi antara lain :. 8211; 70 % iron.

Corrosion | Metallurgical Engineering
https://ivandwisaputra.wordpress.com/sejarah-baja/corrosion
Corrosion occurs in the presence of moisture. For example when iron is exposed to moist air, it reacts with oxygen to form rust,. Fe - - - - Fe. Both water and oxygen are required for the next sequence of reactions. The iron ( 2) ions are further oxidized to form ferric ions (iron “ 3”) ions. Tthe electrons provided from both oxidation steps are used to reduce oxygen as shown. Leave a Reply Cancel reply. Enter your comment here. Fill in your details below or click an icon to log in:.

Corrosion of Aluminum and Aluminum Alloys | Metallurgical Engineering
https://ivandwisaputra.wordpress.com/sejarah-baja/corrosion-of-aluminum-and-aluminum-alloys
Corrosion of Aluminum and Aluminum Alloys. Aluminum owes its excellent corrosion resistance and its usage as one of the primary metals of commerce to the barrier oxide film that is bonded strongly to its surface and, that if damaged, re-forms immediately in most environments. On a surface freshly abraded and then exposed to air, the barrier oxide film is only 1 nm thick but is highly effective in protecting the aluminum from corrosion…. Between these extremes, where the opposing forces reach a reasonable...

https://ivandwisaputra.wordpress.com/sejarah-baja/anodizing
From Wikipedia, the free encyclopedia. These inexpensive decorative carabiners. Have an anodized aluminium surface that has been dyed and are made in many colors. Process used to increase the thickness of the natural oxide. Layer on the surface of metal parts. Anodizing increases corrosion. Effects to reflected light. Anodizing is also used to prevent galling. Of threaded components and to make dielectric films for electrolytic capacitors. Anodic films are most commonly applied to protect aluminium alloys.

Stress Corrosion Cracking of Aluminum Alloys | Metallurgical Engineering
https://ivandwisaputra.wordpress.com/sejarah-baja/stress-corrosion-cracking-of-aluminum-alloys
Stress Corrosion Cracking of Aluminum Alloys. Aluminum alloys that contain appreciable amounts of soluble alloying elements, primarily copper, magnesium, silicon, and zinc, are susceptible to stress-corrosion cracking (SCC). Aluminum alloys that contain appreciable amounts of soluble alloying elements, primarily copper, magnesium, silicon, and zinc, are susceptible to stress-corrosion cracking (. With most service failures specific causes for initiation or propagation of stress corrosion cracks have been...
