Manufacturing method of ultra-high temperature ceramic material based on hafnium carbide and hafnium carbonitride |
| abstract |
The present invention relates to aerospace engineering and materials science. The technical result of the invention disclosed herein with respect to the method is to facilitate and significantly reduce the power and time consumption of material synthesis, and the technical result of the material is to provide a dense ceramic material of non-stoichiometric composition. The technical results are achieved by providing a method for synthesizing ultra-high temperature materials based on hafnium carbide and hafnium carbonitride, the method comprising preliminary mechanical activation of initial hafnium and carbon powders in a high-energy planetary ball mill, in an argon or nitrogen atmosphere. Self-propagating high-temperature synthesis is carried out in the mixture, followed by sintering of the synthesized mixture. Consolidation of the synthetic powder is achieved using a spark plasma sintering method. |
