Texture effect on corrosion behavior of AZ31 Mg alloy in simulated physiological environment

Binary Zr–Ni/Co metallic glass films: Role of the structural state on their durability

“…The corrosion results show that the textured ZrCo film gives better electrochemical characteristics, suggesting that the oxide layer formed on these plans have higher resistance to the electron transfer. This assumption is consistent with results of del Campo et al and Xin et al, who correlated the electrochemical behavior of the surface of magnesium alloys with the dense nature of plans, the latter characteristic being linked to their crystallographic orientation [71,72].…”

Enhanced corrosion resistance of ultrafine-grained AZ61 alloy containing very fine particles of Mg17Al12 phase

“…It has previously been shown that the rate of corrosion of the AZ31 alloy decreases with increasing intensity of the (0 0 0 1) texture [13,14]. This is because the (0 0 0 1) surface has the lowest surface energy and thus dissolves slower than the (1 0 1 0) and (1 1 2 0) surfaces in Mg.…”

“…In addition to chemical factors such as chemical composition, structural factors such as the amount and distribution of secondary phases [11,12], texture [13,14], dislocation density, and grain sizes [15][16][17][18][19] have been shown to significantly affect the microgalvanic corrosion and corrosion barrier properties.…”

Corrosion of Ultrafine Grained Materials by Severe Plastic Deformation, an Overview

“…27,187) It seems that contradicting studies reporting inferior corrosion resistance after SPD of pure magnesium, 116) AZ31, 176,189) (type B) may be attributed to the inhomogeneous microstructures related with dynamic recrystallization. Finally, crystallographic orientation dependency of corrosion is very high in magnesium alloys, 83,[190][191][192][193][194][195][196][197][198] and it seems to have higher impact than grain size. The high atomic coordination of basal plane make the electron working function higher, and has the highest resistance to dissolution.…”
