Abstract
The effect of quenching rate on corrosion and mechanical properties of a novel Na2MoO4@CNT/Al-Zn-Mg-Cu composite is investigated. The results show that the corrosion resistance of this composite is not sensitive to quenching rate, maintaining a low corrosion rate of ∼0.01 mm/y in 0.6 mol/L NaCl solution and the highest resistance to intergranular and exfoliation corrosion. Besides, ultrahigh strength of this composite decreases but the elongation increases greatly with decreasing the quenching rate. The low quenching sensitivity to corrosion results from the formation of protective surface films promoted by surface enrichment of the MoO42- ions spontaneously released from exposed CNTs.
期刊介绍：
Corrosion occurrence and its practical control encompass a vast array of scientific knowledge. Corrosion Science endeavors to serve as the conduit for the exchange of ideas, developments, and research across all facets of this field, encompassing both metallic and non-metallic corrosion. The scope of this international journal is broad and inclusive. Published papers span from highly theoretical inquiries to essentially practical applications, covering diverse areas such as high-temperature oxidation, passivity, anodic oxidation, biochemical corrosion, stress corrosion cracking, and corrosion control mechanisms and methodologies.
This journal publishes original papers and critical reviews across the spectrum of pure and applied corrosion, material degradation, and surface science and engineering. It serves as a crucial link connecting metallurgists, materials scientists, and researchers investigating corrosion and degradation phenomena. Join us in advancing knowledge and understanding in the vital field of corrosion science.
