Effect of alloying elements on the microstructure and corrosion behavior of TiZr-based bulk metallic glasses

Hierarchical Surface Pattern on Ni‐Free Ti‐Based Bulk Metallic Glass to Control Cell Interactions

“…However, it should be noted that XRD may not detect nanocrystalline phases or small‐volume fractions of crystals. [ 6,53 ] Nevertheless, the results of XRD analysis suggest that thermal processing in all conditions tested here does not induce significant crystallization. Figure 2b shows the results of the isochronous DSC analysis.…”

“…[ 15,16 ] Ion release is a by‐product of corrosion, which in turn is generally facilitated by contact with body fluid. [ 6,15 ] Without Ni, Ti─Zr─Cu─Pd BMG systems have improved biocompatibility and sufficient GFA for real‐life applications. [ 14,17,18 ]…”

“…[1][2][3] In addition, owing to their amorphous nature, Ti-BMGs have attractive properties such as high corrosion resistance, wear resistance, lower Young's modulus, higher elasticity, and higher specific strength than traditional crystalline Ti-alloys, making them potential biomaterials for dental and orthopedic applications. [2][3][4][5][6][7] The reduced Young's modulus and enhanced elastic behavior are expected to alleviate stress-shielding effects when contacting bone tissues. [8,9] Indeed, many efforts have been devoted to the development of 𝛽-type titanium alloys achieving low Young's modulus below 80 GPa for crystalline materials.…”

“…[10][11][12][13] In amorphous materials, many Ti-BMGs, such as Ti─Ni─Cu and Ti─Zr─Cu─Ni alloy systems, rely on nickel to improve their glass-forming ability (GFA). [6,14] Several studies have shown that nickel ions can induce harmful effects on the human body, such as cutaneous inflammations and carcinogenicity. [15,16] Ion release is a by-product of corrosion, which in turn is generally facilitated by contact with body fluid.…”

Investigating crevice corrosion of copper and copper alloys using wire beam electrode

“…In general, the spacing of a crevice separates anodic and cathodic regions of corrosion system [7,8]. Therefore, the current moving through the electrolytic resistance between the anodic in the occluded site of crevice and the cathodic at the outer surface, produces an IR drop which has a correlation between the potential of the interior and exterior regions about the crevice [9][10][11][12].…”
