Abstract: | The work presents the experimental results of investigation of the possibility of the creating of high adhesive compound of
chemically noninteracting metals by means of pulse streams of high temperature dense plasma. The 4 kJ plasma focus installation
was used as a source of pulse streams of plasma. In the experiment assemblies of Cu–W and Pb–Fe samples were used. The deep
penetration of atoms Cu and Pb accordingly in W and Fe was found. The mechanisms of the penetration of chemically neutral
atoms into a material of the target can be connected with the following processes: the energy transfer from plasma pulse to
implanting atoms, the origin and distribution of shock waves in the material of a target, and also the Rayleigh-Taylor instability
of the border of two combining materials. |
