文摘
- •
Microstructure affected atmospheric corrosion of Al- and Mg- alloyed zinc.
- •
Materials with finer microstructures were usually more stable.
- •
Mg-rich phases dissolved preferentially.
- •
Al-rich phases activated at cathodic sites at alkali pH.
- •
Al and Mg reduced zinc run-off by stabilisation of protective corrosion products.
