Corrosion of continuous alumina-fibre reinforced Al–2 wt.% Cu–T6 metal–matrix composite in 3.15 wt.% NaCl solution

Corrosion Behavior of Alumina Reinforced Aluminium (6063) Metal Matrix Composites

“…The mass loss profiles ( Figure 1b) however show that the composites have slightly inferior resistance to corrosion (as reflected by the relatively lower weight gain values) in comparison with the unreinforced alloy. Zhu and Hihara [13] have confirmed similar trend in alumina fiber reinforced Al composites; and attributed it to be due to the preferential initiation of corrosion in the alumina/Al matrix interface. The influence of alumina volume percent on the corrosion characteristics was not apparent as the composites exhibited almost the same level of resistance to corrosion.…”

Evaluation of Wear and Corrosion Properties of AA6061/TiB<sub>2</sub> Composites Produced by FSP Technique

“…This indicates that composites will be suitable for sea environments and marine applications. The similar type of observations made by different researchers [23] [24]. The Figure 4 shows the SEM image of 8% composite and base metal.…”

Aluminium reinforced by WC and TiC nanoparticles (ex-situ) and aluminide particles (in-situ): Microstructure, wear and corrosion behaviour

“…The matrix-reinforcement interface, the matrix/ secondary phase interface, the secondary phase nature and content, the reinforcement/secondary phase interface, the electrolyte active ion concentration, the production route, the heat treatment, the surface treatment can significantly affect the corrosion resistance and mechanisms [30][31][32][33][34]. Owing to these too many factors, conflicting data and interpretations exist regarding fundamental issues, such as corrosion resistance and corrosion initiation sites [35]. Several studies have reported lower corrosion resistances for AMCs in comparison with the respective monolithic alloys.…”
