SEM analysis shows that trace amounts of La in Zn–Cu–Ti alloy can eliminate dendritic segregation and produce uniform organization. Analyses of Tafel polarization curves and EIS show that La can obviously improve the corrosion resistance of Zn–Cu–Ti alloy. Zn–Cu–Ti–0.5La alloy has the best corrosion resistance. The corrosion of the investigated alloys is mainly selective.
- The effect of environmental factors on long-term atmospheric corrosion behavior of commercially pure aluminum AA1035

Atmospheric corrosion of pure aluminum AA1035 exposed for 20 years in rural environment with high Cl− deposition (Qionghai), urban (Beijing), coastal (Wanning), and industrial (Jiangjin) environments was investigated. In urban and industrial environments pitting corrosion occurred on AA1035, and in rural and coastal environments AA1035 suffered intergranular corrosion. Therefore, the corrosion behavior of AA1035 varied in different environments.
- Effect of welding flash on the corrosion of friction stir spot welded AZ31B
Y. Savguira, W. H. Liu, T. H. North and S. J. Thorpe
Version of Record online: 18 OCT 2016 | DOI: 10.1002/maco.201609182
The present is the first report investigating the role of welding flash in the corrosion of friction stir spot welded AZ31B through a combination of various complimentary techniques; mass loss testing, scanning reference electrode technique, and microcapillary polarization. Removal of the welding flash could reduce the corrosion rate of the joint by as much as 20%.
- The oxidation behaviour of the pulse plasma sintered β-NiAl intermetallic compound under thermal cycling conditions at 1150 °C
J. Jedliński, J. Dąbek, J. Prażuch, A. Michalski, M. Rosiński, J.-L. Grosseau-Poussard, D. Takashima, W. Wołczyk and Z. Żurek
Version of Record online: 17 OCT 2016 | DOI: 10.1002/maco.201508804
The effect of microstructure engineering using a new manufacturing route (pulse plasma sintering) on the high temperature oxidation behaviour of β-NiAl coating material with and without small amounts of Hf was determined at 1150 °C under thermal cycling conditions in air. The results showed that the Hf-containing materials behaved better than Hf-free ones.
- A novel methodology to study localized corrosion under atmospheric simulated corrosion conditions: Toward a continuous monitoring of the corrosion damage on AA2024
R. Oltra, L. Colard and R. Bonzom
Version of Record online: 17 OCT 2016 | DOI: 10.1002/maco.201609151
A well-controlled spray generated by an ultrasonic nozzle focused on the surface of very thin AA2024 foils positioned in a compact test cell is proposed which renders possible the access to the backside of the target. Validation in terms of corrosion damage of remote sequential experimental procedure using a ultrasonic nozzle programmed to pulse is illustrated.
