Owing to the COVID situation and transfer of manuscripts from ITSC 2020; this paper presents a shortened version of experiments and results that were recently published in a standard journal.

One of the major challenges are the materials used for construction of the main reactor vessels. In tokamaks; torus-shaped fusion facilities confining the hot plasma by strong magnetic fields; the innermost chambers are to be coated with dense coatings of W-based alloys. So far; the attempts for such coatings formation by other methods failed due to oxidation; high porosity; insufficient adhesion; high specific surface; or even insufficient thickness below 10 μm. Cold spraying seems a promising technology for the task. Here we demonstrate a successful fabrication of thick W; W-Cr and W-Cr-Ti coatings prepared without oxidation of the metals. For the first time in history; a deposition of 80 μm-thick coating of pure W was achieved.
