Tungsten Nanocomposites Reinforced with Nitride Ceramic Nanoparticles and Fabrication Process Thereof

摘要

PURPOSE: Tungsten nanocomposites reinforced with nitride ceramic nanoparticles and a method for fabricating the same are provided to uniformly nitride ceramic nanoparticles in a tungsten matrix by arranging the pre-set ratio of the nitride ceramic nanoparticles in the tungsten nanocomposites. CONSTITUTION: Nitride ceramic nanoparticles are uniformly dispersed in a tungsten matrix. A mechanical alloying method using high energy milling process is implemented to the mixture to obtain tungsten nanocomposites reinforced with nitride ceramic nanoparticles. 0.1 to 50 volume% of the nitride ceramic nanoparticles are arranged in the tungsten nanocomposites reinforced with nitride ceramic nanoparticles. The nitride ceramic nanoparticles include one or more selected from a group including ZrN, HfN, BN, AlN, Si_3N_4, TiN, TaN, Ta_2N, VN, CrN, Cr_2N, Mo_2N, NbN, WN, and W_2N.
