1. without magnetic gradient structure Ti (C, a N) based ceramic metal, with TiC, TiN, Ni, Mo 2c, WC and Cr 3c 2powder, as raw material, is prepared from through the surfaces nitrided processing of ball mill mixing, die forming, vacuum degreasing, vacuum sintering and hot isotatic pressing, it is characterized in that:

  • Prepared without in magnetic gradient structure Ti (C, N) sintering metal, the weight percent of each chemical composition is;

    Ti35~

    49%, Ni15~

    35%, Mo14~

    20%, W0~

    4%, Cr0.4~
