钨(W)因其熔融温度高、导热性好、溅射率低而成为熔合装置中等离子体面对材料的首选材料，真空等离子体喷涂（VPS）技术适用于大面积无脆性夹层，但W层的导热性很差，容易脱落，这主要是由于其多孔结构。采用搅拌摩擦处理（FSP）改善了VPS-W涂层的性能，表明FSP可以显著改善VPS-W涂层的力学性能和热性能。
Tungsten (W) is the primary candidate material as a plasma facing material in fusion devices, as for its high melting temperature, good thermal conductivity and low sputtering rate, and vacuum plasma spray (VPS) technique is preferred as it is applicable for large area without brittle interlayer, but the thermal conductivity of W layer is very poor, and easy to detach, mainly caused by its porous structure. W Friction stir processing (FSP) was applied on VPS-W to improve these poor properties, and it was suggested that FSP can contribute to significant improvement in both mechanical and thermal properties of the VPS-W coating.
