Method of toughening the structure of a diamond or diamond-like coated tool, by the steps of: (a) depositing, by low pressure CVD, a plurality of layers of separated diamond or diamond-like particles onto a nondiamond or nondiamond-like tool substrate (i.e., SiAlON, Si3N4, SiC, Si, Ti, Co cemented W
Method of toughening the structure of a diamond or diamond-like coated tool, by the steps of: (a) depositing, by low pressure CVD, a plurality of layers of separated diamond or diamond-like particles onto a nondiamond or nondiamond-like tool substrate (i.e., SiAlON, Si3N4, SiC, Si, Ti, Co cemented WC, TiC, Ni-Mo cemented TiCN), the substrate being selected to facilitate diamond or diamond-like deposition and to retain its strength-related properties after such CVD; and (b) interposing a mechanically adherent, planarized binding material (i.e. transition metals, silicon, boron) between and on said layers of particles and across the separated particles of each particle layer, said binding material being substantially devoid of diamond graphitizing or dissolution agents. A barrier layer is deposited onto said tool substrate prior to step (a) to prevent the egress of chemicals capable of graphitizing diamond or diamond-like particles. The total thickness of the coating structure is about 50-125 microns.
