“…During the last few decades, rapidly solidified (RS) Al-alloys have been attracting significant attention due to improved properties (such as mechanical behavior and corrosion resistance) in relation to conventional Al alloys [1][2][3][4][5][6][7][8][9][10]. Rapid solidification processes (RSP) can produce many metastable phases, such as supersaturated solid solutions, intermediate phases and metallic glasses.…”

“…Yoshioka et al [9] studied the corrosion The present effort presents the comparative corrosion behavior of Al-Co alloys of various compositions in the Al-Al 9 Co 2 side of the Al-Co phase diagram [36] prepared by vacuum arc melting, with the aim to determine the Co content that leads to the highest corrosion resistance. The Al-Al 9 Co 2 region of the Al-Co phase diagram was selected with the aim to attain a two-phase structure (Al + Al 9 Co 2 ) that could combine the aforementioned beneficial features of Al 9 Co 2 , as a CMA in situ reinforcement, with the ductility/toughness of Al, as a matrix to brittle Al 9 Co 2 . The final objective (addressed in a future publication) is to determine the lowest Co content that could lead to an optimum combination of attributes, such as corrosion resistance, ductility, wear resistance, specific weight and cost of raw materials.…”

“…The beneficial effect of Ni as a solute in the pitting resistance in rapidly solidified chemically homogeneous Al-Si-Ni ternary alloy has been reported previously (3). The addition of Ni into Al-Si (5 at%) alloys showed a linear increase of pitting potential as a function of concentration in at%.…”

“…It has been reported that the pitting potential of the amorphous (Al 75 Cu 17 Mg 8 ) 100-x Ni x alloy was further ennobled by additions of Ni up to 5 at% (15). In rapidly-solidified Al-Si-Ni alloys, the increase in Ni content up to 6 at% also enhanced the pitting potential (3). However, it is unexpected that a small addition of Ni used to enhance the GFA has a stronger effect on localized corrosion resistance than the addition of greater amount of Cu in solid solution.…”

“…It is generally reported that amorphous iron-chromium alloys have superior anti-corrosion ability. 29) This extremely high corrosion resistance of the amorphous iron alloys containing 8 at% or more chromium has been interpreted in terms of the rapid formation of thick, uniform, highly corrosion resistant passive film because of the characteristics of the amorphous alloys. When amorphous alloy coatings on the steel were used to prevent corrosion, the passive film formed on the amorphous alloy consists mainly of hydrated chromium oxyhydroxide, which is a common major constituent of stable passive films on ordinary stainless steels.…”
