Metal glasses, also known as metallic glasses, offer significant benefits in various applications, primarily due to their exceptional material properties. The most notable advantage is their outstanding corrosion resistance.
Key Advantages of Metallic Glass
Outstanding Corrosion Resistance
Metallic glasses are highly valued for their remarkable ability to resist degradation in diverse and challenging environments. They present outstanding corrosion resistance in a variety of hostile environments [117]. This superior characteristic means they can withstand chemical attacks, oxidation, and rust far better than many conventional metals and alloys.
- Durability in Harsh Conditions: This property makes metallic glasses ideal for components exposed to corrosive elements, such as saltwater, acids, or industrial chemicals, significantly extending their service life and reliability.
- Reduced Maintenance: Their resistance to corrosion translates into lower maintenance costs and less frequent replacements for parts used in corrosive settings.
Enhanced Material Protection Through Cladding
A direct and significant advantage stemming from their excellent corrosion resistance is their utility in cladding applications. Metallic glasses can be effectively used to coat or 'clad' other materials that possess lower inherent corrosion resistance.
- Protecting Common Metals: Materials like carbon steels or low-alloy steels, which are widely used due to their strength and cost-effectiveness but are susceptible to corrosion, can be protected by a thin layer of metallic glass.
- Synergistic Benefits: By applying metallic glass as a cladding, the underlying bulk material benefits from the high corrosion resistance of the metallic glass, while retaining its original mechanical properties and cost advantages. This method presents obvious advantages for improving the performance and longevity of less noble materials in corrosive environments.
