| titleOfInvention | Promote the metal ceramic wear-resisting material preparation method of carbon diffusion based on carbide former |
| abstract | The invention discloses a kind of metal ceramic wear-resisting material preparation methods promoting carbon diffusion based on carbide former, it is characterized in that first keeping the temperature 1~2h at 500~700 DEG C, form the cermet green body of carbide-containing formation element；Then by Al 2 O 3 Coat TiH 2 Core/shell structure powder, thickness is less than 3nm, the number of plies is less than 3 layers and specific surface area and is more than 250m 2 The graphene of/g, Na 2 CO 3 Three kinds of substances in percentage by weight 3:2:1 mixed preparing goes out hydrogeneous carburizing medium；Again by green compact be embedded to it is in hydrogeneous carburizing medium and under 5 ~ 15MPa pressure consolidation；Liquid-phase sintering is finally carried out, promotes carbon diffusion to prepare metal ceramic wear-resisting material based on carbide former.It grows up the present invention overcomes crystal grain existing for prior art the problem serious, carburizing time is long, efficiency is low, metal ceramic wear-resisting material preparation is realized in sintering process. |
