Methods of Increasing Thermal Conductivity of Plasma Sprayed Tungsten-Based Coatings
Original language description
Tungsten is the main candidate material for the armor of plasma facing components for ITER and future fusion devices. Plasma spraying is an alternative method for manufacturing tungsten-based coatings, including composites and graded layers, having a number of advantageous features. On the other hand, the main limitation to application of these coatings on high heat flux components, is their low thermal conductivity, originating in the layered structure. This paper is focused on four methods of improving the coatings? thermal conductivity. First method consists in modification of the basic spraying parameters, which have a direct influence on the coating structure and therefore properties. The other three methods involve post-processing of the coatings: molten copper infiltration, laser remelting and densification by HIPping. The latter encompasses also tungsten-copper composites of various compositions. Experimental results, including structural and thermal characterization,
