Numerous obstacles are still to be resolved in the process of using power sources based on nuclear fusion. 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 inner-most chambers are to be coated with dense coatings of W, or W-Cr-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. In our study, we demonstrate a successful fabrication of thick W, W-Cr and W-Cr-Ti coatings prepared without oxidation of the metals. To date, the produced mixed coatings contained the highest levels of W ever achieved. Even more importantly, a deposition of 80 µm thick coatings of 100% pure W was demonstrated for the first time too. All coatings exhibited high hardness levels, good interface quality with substrates of three different hardness and, importantly, a promising potential for desirable oxidation resistance by formation of Cr2WOx scales.
