FIELD: technological processes. n SUBSTANCE: group of inventions relates to formation of a support substrate for a cutting element, the formation of a cutting element, a structure for a rock cutting tool and a rock cutting tool. Method of forming a support substrate for a cutting element comprises forming a precursor composition comprising discrete WC particles, a binder and discrete particles containing Co, Al and one or more of C and W, subjecting the precursor composition to a densification process using a seal temperature higher than or equal to the discrete particles transition temperature. n EFFECT: formation of a densified structure containing WC particles dispersed in a homogenised binder containing Co, Al, W and C. n 15 cl, 21 dwg, 37 ex |
