This paper presents a method for producing a hard alloy WC-5TiC-10Co with a density equal to 100% of the theoretical value, a hardness of 1484 HV, and a bending strength limit of 1924 MPa. The high quality of the product is ensured by original research method based on the mechanochemical synthesis of WC and TiC powders using available precursors. and the implementation of high-speed SPS consolidation of the obtained powder while achieving a high degree of packaging with a minimum grain growth at 1200 °C and processing time no more than 13 min. Experimental data on seal dynamics, phase composition, morphology and mechanical properties of WC-5TiC-10Co using SPS in the range 1000 to1200 °C are presented.
