Abstract

Material and power techniques for producing solid three-dimensional materials. In one aspect, a composite material is based on a quasicrystal powder of an Al—Cu—Fe system with a nickel binder, the composite material containing a reinforcing nickel lattice. In a second aspect, the composite material is obtained by applying a nickel coating to quasicrystal powder particles of an Al—Cu—Fe system. The quasicrystal powder can be treated in plasma to form a thin (10-20 nm) nickel coating on the surface of the powder particles. The treated powder, which is a dispersed composite material, can then be pressed at room temperature under quasi-hydrostatic conditions at a pressure of more than 1.5 GPa. In some aspects, the improved characteristics of the three-dimensional materials include providing three-dimensional fully dense composite quasicrystal materials with improved mechanical properties, a decreased coefficient of friction and increased resistance to mechanical wear, and creating additional possibilities for new technological applications.
