Abstract
The corrosion and erosion-corrosion behaviors in the weld heat-affected zone (HAZ) of Hadfield steels with varying Cr contents (1, 2, and 3 wt%) were examined. Various experimental methods, including electrochemical polarization, impedance, and weight loss measurements, were utilized. Two types of isothermal heat treatments were conducted in a box furnace..... More

Abstract
The effects of the electrogalvanizing conditions (a combination of plating current and time) on hydrogen infusion, embrittlement, and corrosion-induced hydrogen embrittlement (HE) behaviors of ultra-high strength steel were examined. A range of experimental and analytical methods, including electrochemical impedance spectroscopy, hydrogen permeation, polarization, and slow strain rate test, were employed...... More

Abstract
To clearly understand the effect of the eutectic structure in the Zn-Al-Mg alloy coating on the corrosion behaviors in chloride containing aqueous environments, a bulk Zn-MgZn₂ sample was fabricated by diffusion bonding process, and a variety of experiments, such as electrochemical polarization and galvanic corrosion measurements, salt spray tests, and.....

Abstract
The effects of alloy composition on the coating structure and corrosion resistance of hot-dip Znbased alloy coated steel products were investigated. Zn-based alloy coating layers with different Al and Mg compositions were fabricated using a batch-type galvanizing simulator. Various intermetallic compounds including Zn, Zn/MgZn₂ binary eutectic, Zn/Al binary eutectoid and..... More

Abstract
The incomplete elimination of oxide scale formed during the normalizing process can result in severe degradation of the surface and mechanical properties of ultra-strong steels. This study revealed that the formation of oxide scale was highly dependent upon the alloying elements Ni and Cu. Ni-bearing steel showed a much higher..... More
