ABSTRACT

The main regularities of Al and Ni surface alloying by means of compression plasma flows treatment of Ti/Al and Zr/Ni (coating/substrate) systems were investigated in this work. X-Ray diffraction, Rutherford backscattering and scanning electron microscopy were used as investigation techniques. It was found that a mixed layer contained intermetallides (Al3Ti, Al2Ti or Ni5Zr) and nitrides (AlN, TiN or ZrN) providing microhardness increase. The phase composition of the mixed layer is correlated with the phase composition given by the equilibrium phase diagram. Thus, compression plasma flows can be effectively used for the predictable formation of a variety of alloys in the surface layer of metals by means of “coating/substrate” system treatment.
