Interface topography and residual stress distributions in W coatings for fusion armour applications

Abstract:

Vacuum plasma sprayed (VPS) tungsten (W) coatings are potential plasma facing components in future fusion power plants. However, the large coefficient of thermal expansion mismatch between W and underlying structural steels and other metallic materials poses a significant problem for manufacturing and service life because of the evolution of large thermally induced stresses leading to failure. In this paper, the effects of the substrate/coating interface 3D geometry on stress distributions ar...
