Abstract
The effect of TiC on corrosion process, particularly the passive and initial stages, is unclear. The passivation and initial corrosion of 2024-TiC AMCs are investigated in this report. It is found that a small amount of TiC improves corrosion resistance by reducing galvanic corrosion current density and forming a stable passive layer with low Cl⁻ adsorption and cation vacancy density, minimizing dissolution. However, excessive TiC causes uneven distribution, aggregation of Cl⁻, and passive film rupture, leading to anode aluminum dissolution and accelerated pitting corrosion propagation. These findings highlight the balance requirement for optimal TiC additive used in enhancing corrosion resistance.
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.
