Quasi-crystalline alloys are a unique material structure with anomalous properties that make them ideal for use as surface coatings on soft metals. Due to their multifaceted symmetry and high strength, such alloys can significantly increase the wear resistance and corrosion resistance of base metals, which is especially important in aggressive operating conditions. When applying a quasi-crystalline coating to soft metals such as aluminum, copper and light alloys, it is possible to significantly improve their performance characteristics. Quasicrystals form a strong chemical and mechanical bond with the substrate, which minimizes the risk of coating peeling.
One of the advantages of quasicrystalline alloys is their ability to reduce friction, making them ideal for use in high-stress environments. Technological processes such as laser deposition and PVD (vapor deposition metallurgy) ensure reliable and uniform application of these coatings.
Thus, the use of quasicrystalline alloys opens up new horizons for improving the durability and reliability of soft metals in various industries.
The use of quasi-crystalline coatings allows the creation of encapsulated surfaces that reduce friction and, therefore, increase the service life of products. In addition, their low thermal conductivity contributes to the thermal protection of soft metals, preventing their deformation at high temperatures.
The development of technologies for applying such coatings to soft metals opens up new horizons in mechanical engineering and materials science. Improvements in additive manufacturing and vacuum deposition methods will ensure the homogeneity and durability of quasi-crystalline coatings, thus strengthening the memory of revolutionary changes in the field of metal protection and application.
