Quasicrystalline structured materials bear singular properties such as elevated hardness, low superficial energy, low friction coefficient, good oxidation and corrosion resistance, high degrading resistance as well as low electrical and thermal conductivities. These materials can be obtained via conventional foundry, high energy grinding or mechanical alloying as well as fine film techniques. Nonetheless, these materials are very fragile. This makes bulk rods as used for mechanical components making also difficult. Therefore, most applications use the powder form as reinforcement in composite material and plasma spray superficial layers. One of the techniques that show excellent results is the high energy grinding technique of such quasicry...
