abstract = {In the course of developing functionally graded
tungsten/steel-layer systems as protective coatings for the
first wall (FW) of future fusion reactors, an overview of
the results attained so far is given. This includes the
determined parameters for creating such systems by vacuum
plasma spraying on a laboratory scale and the achieved
material properties determined in previous works. To realize
the coating of future full scale FWs as well, the coating
process is adapted to larger coating areas in the form of
mock-ups. For such components, special attention needs to be
paid to the challenges of the limited temperature window
during coating to achieve good coating adhesion, whilst
avoiding exceeding the tempering temperature of the steel.
One successfully coated mock-up is also exposed to
fusion-relevant heat loads in HELOKA (Helium Loop Karlsruhe)
to evaluate the coating system behavior and verify its
durability. Finally, for even larger components the coating
design and process are further optimized, supported by
finite element simulations.},
