Quasicrystals are a special class of materials with unusual properties, such as an aperiodic crystal structure and high thermal stability. One of the most studied types of quasicrystals are Al-Cu-Fe quasicrystals. They attract the attention of researchers with their unique structure and properties.

Al-Cu-Fe quasicrystals are highly resistant to corrosion due to their specific structure, but over time they can be subject to various influences leading to the destruction of their structure. Corrosion mechanisms for quasicrystals include chemical corrosion, electrochemical corrosion, as well as stress corrosion and high temperature corrosion.

The composition and structure of Al-Cu-Fe quasicrystals have a significant impact on their corrosion resistance. Changes in elemental content, microstructure and defects can lead to altered corrosion response and accelerated degradation processes.                                                    

Various methods are used to protect quasicrystals from corrosion, including varnishing, electroplating, coating with protective films, surface modification and the use of anti-corrosion additives. It is important to consider the specifics of the material and operating conditions when choosing the optimal protection method.

Thus, the study of corrosion of Al-Cu-Fe quasicrystals and their related crystalline phases has provided valuable data on the influence of the environment on the structure and properties of these materials. Further research in this area could lead to the development of new ways to protect against corrosion and improve the durability of quasicrystals.

Corrosion of Al-Cu-Fe quasicrystals and their related crystalline phases is a complex and multifaceted process that requires in-depth knowledge and experience for effective control and prevention. Understanding the mechanisms of corrosion, the influence of composition and structure, as well as the use of modern protection methods will help ensure the durability and reliability of materials based on quasicrystals.
