Prestressed Reinforcement

Using electrochemical impedance spectroscop (EIS) and polarization curve technique, the electrochemical behavior of prestressed reinforcement under different stress levels was studied in simulated concrete solution. The results show that: As the stress increasing, the impedance spectroscopy changes significantly, the entire impedance spectroscopy shows an elongated semi-circular deformation, high-frequency capacitance arc radius corrosion decreases with the corrosion progress, in other words, the reaction resistance decreases, the corrosion rate of the sample increases. And when the galvanized steel is in 1064MPa stresss condition, corrosion current density reaches the maximum, is 9 times larger than that of none stress corrosions condition. Under the combined effects of the external stress and corrosive media, dislocation can be emitted, value-added and moves. When it reached a critical state, it would lead to the crack nucleation of Stress corrosion cracking (SCC).

Aluminum Alloy Surface

The preparation method of the superhydrophobic surface on aluminum alloys was investigated, the method is novel by phosphoric acid-dichromate process and stearic acid coating, superhydrophobic aluminum alloy surfaces were successful prepared, the maximum static water contact angle and sliding angle on the superhydrophobic surface was 151±1.8° and 10°, respectively. In this work, the microstructure and self-cleaning properties of the superhydrophobic surface were studied. The superhydrophobic surface is a factor to reduce device-associated contamination and can be used in metal packaging practice.

The Impact

Galvanizing also denoted as zinc coating is a scientifically approved method applied to protect iron and steel against the effects of corrosion. In the galvanization process, aluminum is added with zinc. Zinc has numerous properties under different environmental conditions. These properties are subject to change when it comes to the coating process. The common properties here may include its appearance, hardness, the thickness along with other mechanical and physical properties. Due to these properties, there may also be inconsistency on the coating structure. So the addition of aluminum unto zinc, will ensure that various properties are eliminated for the better improvement of the zinc coating process. Aluminum possesses stronger mechanical properties and therefore valid for the coating process. It ensures that zinc is not arrived at by the corrosion agents. In this study, the focus will largely be based on the impact of aluminum on corrosion behavior as aligned to hot-dip galvanized steel. However, in this study, the galvanization process was performed using the dry process. The percentage variation of zinc resulted in different results in the rate of corrosion. The hardness of zinc thus increased via additional of aluminum percentage.
