%X Functionally graded steel/tungsten layers may be used as interlayers in the first wall of future fusion reactors tobalance thermally-induced stress peaks in the steel‑tungsten joint. In this work, a modified water-stabilizedatmospheric plasma spraying set-up is used to deposit uniform and functionally graded steel/tungsten coatings atelevated substrate temperatures. Uniform coatings were used to characterise individual sublayers of gradedcoatings in detail. The thermal expansion, thermal conductivity, Young's modulus and yield strength of thelayers are promising for the application in steel‑tungsten joints and can be explained by microstructural observations.Only at a substrate preheating temperature of 900°C the formation of intermetallic precipitatesduring deposition was observed.
