Tic Carbide Production Process
Author: langfeng Time: 2017-03-22
Tic carbide production process is TiC, Ni and Mo (or Mo2C) together with wet grinding, green compact usually in the vacuum at 1300 ~ 1500 ℃ for liquid phase sintering; can also be infiltration method and high temperature from Spread synthesis method. TiC-Mo2C Ni alloy was prepared by infiltration method. The TiC porous sintered body (skeleton) was prepared by infiltration method. Then, Ni, Mo melt was used to melt the skeleton to form dense sintered body. TiC-Mo2C was prepared by high temperature self-propagating method Alloy, the titanium powder, carbon black, molybdenum powder and nickel powder were kneaded, dried and pressed, and then subjected to high temperature self-propagating reaction in the graphite mold and maintained at a load of 0.05 MN after the combustion wave was passed 6 ~ 10s. TiCN Carbide is essentially a variant of Tic Carbide, and its preparation process is essentially the same, including the preparation, forming, sintering or hot pressing of the mixture. When the mixture is prepared, Tic and TiN can be mixed with TiC and TiN Can be added in the form of Ti (C, N) solid solution.
