• potential ceramic-based PFC materials, specifically tungsten carbide (WC) thin films and their nanocomposite counterpart, WC–WO3, under 100 keV Kr+ ion irradiation. The films were irradiated at fluences of 1 × 1016, 3 × 1016, and 1 × 1017 ions/cm2. Rutherford backscattering spectrometry was employed to

• -facing materials; sputtering erosion; WC–WO3 nanocomposites; Introduction Tungsten carbide (WC) and tungsten trioxide (WO3) are two hard and high-temperature-stable compounds that have individually demonstrated exceptional properties, including high melting points, mechanical strength, and chemical
