Effects of Fiber and Silicon Contents on Corrosion Behavior of Alumina Fiber-Reinforced Al-Si Alloys in Sulfuric Acid Aqueous Solution

A Comparative Study of Corrosion Behavior of Al/SiCp Composite with Cast Iron

“…This is because, although pits are formed, their growth is restricted by the presence of particulate and also the effective area offered by the matrix for corrosion to take place is reduced. [13][14][15][16][17][18] However, a third group reports that corrosion resistance of the alloy is unchanged by the reinforcement of particulate on the basis of the above two counter phenomena; severity of IPD is balanced by the reduction in metallic area exposed to the corrosive media. [21][22][23] Aluminum was confined to the marine environment and was compared to the matrix alloy in the previous studies.…”

“…However, most of the attempts made to understand the corrosion mechanism in AMC were limited to marine environments. [13][14][15][16][17][18][19][20][21][22][23][24] Very few studies have been done in other environments. [25][26] In accordance with these investiga-tions, localized corrosion is taking place in AMC through a number of possible phenomena, such as galvanic coupling between the reinforcement and the matrix or the precipitate and matrix, pitting corrosion, crevice corrosion caused by discontinuity in the passive film, etc.…”
