Product Description

Results of experiments on reception and studying of properties multilayered Ti/TiN and Zr/ZrN coverings on alloy Zr1Nb are presented at their sedimentation from plasma of the vacuum-arc discharge. Are received «unloaded» multilayered Ti/TiN and Zr/ZrN the condensates consisting of alternating soft, plastic thin layers of pure titanum and zirconium and firm thin layers of their TiN and ZrN nitrides. Multi-layer Ti/TiN and Zr/ZrN condensates differ from thick nitride coverings by smaller internal stress, absence of cracks, high adhesion to a substrate and between layers. Properties multilayered Ti/TiN and Zr/ZrN condensates are studied: electrochemical behaviour with the help a potentiostatic method and corrosion behaviour with the help of corrosion tests in autoclav with approximate to reactor conditions. Also mechanical properties of multilayered condensates are studied by means of a method nano-indentering. Received gradient nanostructure Ti/TiN and Zr/ZrN condensates differ by the raised hardness and corrosion firmness. Influence of an irradiation by ions Ar+ on corrosion of multilayered condensates is considered.
