“…Composition difference results in different types of oxides on powder surface, and the phase composition inside the powders, such as SAC (β-Sn matrix + Ag3Sn + Cu6Sn5 intermetallic compound particles) [4], SnBi alloys (Sn-rich + Bi-rich phases) [5], SnIn alloys (In3Sn + InSn4 phase) [6] etc. Taking Sn58Bi as an example, due to the significant difference in standard electrode potential between Bi (0.307 V) and Sn (-0.137 V), the corrosion resistance of Sn58Bi alloys during storage is relatively poor [7]. Similarly, we found that significant corrosion occurs in Sn58Bi solder paste fabrication process during the mixing of the powder and flux.…”

“…Although there are some reports on the corrosion behavior of Sn in carboxylic acid solutions as the activators in application, research on Sn-Bi and Sn-In incarboxylic acid is less studied. For Sn-Bi alloys, our previous study focused on the corrosion behavior of Sn-58Bi alloys in different concentrations of DL malic acid solution using electrochemical and physical methods [7]. The results indicate that the thin film formed on the surface of Sn-58Bi alloy is a p-type semiconductor composed of SnO2 and nonstoichiometric SnOx (1< x <2).…”

The corrosion behavior of pure Sn, Sn2Ag, Sn42In and Sn58Bi alloys in 5 wt.% citric acid solutions has been investigated using electrochemical noise analysis combined with potentiodynamic polarization, electrochemical impedance spectroscopy tests and etching morphology observation. The results indicated that Sn58Bi has the lowest corrosion rate, followed by Sn2Ag, Sn42In, and Sn. The corrosion evolution of the four alloys mainly consists of two stages as follow：for pure Sn, the first stage is local corrosion (corrosion pits growth) stage and the second stage is uniform corrosion with preferential dissolution of some grains on the sample surface. In contrast, for dual phase alloys, Sn2Ag, Sn42In, and Sn58Bi alloys, all preferentially underwent selective phase corrosion in the first stage, followed by the growth of uniform corrosion and selective phase corrosion in the second stage. The corrosion incubation rates for the four Sn-based alloys: Sn42In > Sn > Sn2Ag > Sn58Bi for both uniform corrosion and local corrosion. While the probability of corrosion growth in sequence was: Sn > Sn58Bi > Sn42In > Sn2Ag (uniform corrosion), Sn58Bi > Sn > Sn42In > Sn2Ag (local corrosion). In this work, the corrosion behaviors were consistent with the observed corrosion morphology, which provided guidance for understanding the interaction between solder alloys surfaces and acid in flux and further selecting organic acid activators compatible with new solder alloys.

“…Therefore, Bi-based LM has a corrosive behavior in acidic solutions. 76 Metal Bi and its alloys also show tremendous potential in catalytic applications owing to their unique structural characteristics. They can not only catalyze the production of gluconic acid by oxidation reaction but also electrochemically reduce CO 2 to formate.…”

The cavitation erosion behaviors of Fe-19Cr-15Mn-0.66N high nitrogen austenite stainless steel in distilled water and 0.5 mol/L NaCl were investigated by conducting mass loss and electrochemical measurements. The mass loss of HNSS after CE for 8 h in 0.5 mol/L NaCl solution is 1.15 times of that in the distilled water. The magnitude of impedance decreased within 5 h and then leveled off with a slow decrease. Cavitation erosion has a significant effect on the composition of the passive film, resulting in a notable increase in the Cr2O3 and Fe2O3.
