文摘
- •
Gd-based bulk metallic glass prepared at higher superheat temperature gradually shows better corrosion resistance and reaches the best at 1105 °C.
- •
No pitting corrosion occurs in 3.5% NaCl solution for all Gd-based bulk metallic glass.
- •
Superheat treatment could be a method to improve corrosion resistance of metallic glass.
