The structure-phase state formation in a zone of pulse laser processing of aluminum alloys is investigated in the work; the micro-hardness distribution in them is also investigated. Experimental data concerning influence of modes of laser processing on a structural state of alloys are received. The laws of structurization in aluminum surface layers are established at pulse laser alloying by powders mixture of copper and cobalt in an atomic parity one to one. It was shown, that in a zone of laser alloying the quasi-crystalline phase formation is possible that leads to increase of micro-hardness values in tens times. The structural state quasicrystal aluminum-based alloys are characterized of high thermal stability relative to thermal treatment. The identification quasicrystaline phases was simplified due to algorithm modeling crystal and reciprocal lattice. The results can be used at development obtaining technologies wear resistant quasicrystal coating of metallic device. The scope is physics of amorphous condition of substance, metallurgy, mechanical engineering.
