Ion Implantation Study of Tungsten Alloys as Plasma Facing Components

Tungsten-Copper-Nickle (W-Cu-Ni) and Tungsten-Tantalum (W-ta) are considered as Plasma facing components (PFCs) as several adverse effects such as embrittlement, melting, and morphological evolution has been observed in W when it is bombarded by low-energy and high-fluence Helium(He) and Deuterium(D) Plasma. (W-Ta) alloys showed better resistance as compared to pure tungsten under simulated fusion plasma conditions. W-Ni-Cu alloys are machinable grades referred to as heat sink material and selected due to their high fracture toughness and tensile strength compared to pure tungsten.
