英文摘要Tungsten (W) coating plasma facing material (PFM) was fabricated on the copper (Cu) substrate by a plasma spraying technique, and the properties of the coating were characterized, including the coating porosity, the theoretical density, the bonding strength between tungsten coating and copper substrate, the thermal conductivity, and the Vickers micro-hardness distribution. And the damage evolution of the tungsten coatings with both of the direct and in-direct cooling condition was also investigated. The results indicate that the failure of W PFM with the direct cooling is attributed to the delamination between the lamellar layers, not the surface damage. The damage evolution of W PFM is as follows: the columnar crystals grow up, micro-cracks appear between the lamellar layers, then the lamellar rayer delaminates and finally W PFM fails. But under the indirect cooling, the heat flux performance of W PFM is limited to 7.5 MW/m(2), while that of the direct cooling W coating is 10 MW/m(2). The main failure behavior is W coating detachment from Cu substrate, which is induced by Cu melting.
