On the Hydrogen Permeability and Adhesion of TiN/Ti Coatings Produced on Zr–1% Nb Alloy by Vacuum Ion-Plasma Methods

Thin films of TiN are deposited onto Zr–1% Nb alloys using vacuum-arc plasma in two steps. First, the plasma-immersion ion implantation (PIII) of titanium is implemented; then, without interrupting the experiment, the vacuum-arc deposition (VAD) of TiN is carried out. The VAD and PIII modes for obta...

Description
Summary:Thin films of TiN are deposited onto Zr–1% Nb alloys using vacuum-arc plasma in two steps. First, the plasma-immersion ion implantation (PIII) of titanium is implemented; then, without interrupting the experiment, the vacuum-arc deposition (VAD) of TiN is carried out. The VAD and PIII modes for obtaining the most effective coating (from the viewpoint of protecting the substrate from corrosion and hydrogen embrittlement) have been previously determined. Within studies of the mechanical properties of the obtained coatings, a study of changes in the adhesion of coatings under Arctic conditions (at a temperature of –20°C, seawater ice) and hydrogenation of the samples is carried out. It is established that coatings that are frozen in seawater ice for 24 hours without preliminary saturation with hydrogen have the best adhesive strength. The mechanism of the established effect is briefly discussed.
