Sintering Mechanisms

Functionally graded cemented carbides of two types are described. The functionally graded cemented carbides of the first type are of the WC-Co system and comprise gradients of WC grain sizes and/or Co contents. The functionally graded cemented carbides of the second type are Ti-and N-containing cemented carbides comprising gradients of nitrogen, cobalt and Ti-based cubic carbides. Special features and applications of the functionally graded cemented carbides of the both types are presented. Sintering mechanisms explaining the gradient formation in the functionally graded cemented carbides of the both types are summarized.

Diamond coatings have been deposited by plasma enhanced chemical vapor deposition (PCVD) onto WC-Co cemented carbides by use of specially developed barrier interlayers, well compatible with cemented carbides. The barrier interlayer comprises a Ti-based layer adjacent to the substrate, which completely prevents both substrate decarburization and Co diffusion from the substrate, and a diamond-bonding layer needed to obtain high adhesion to the diamond coating. The diamond-bond layer is obtained by seeding the surface with nanograined diamond particles by laser ablation. Diamond deposition under controlled parameters allows one to obtain fine-grained and uniform diamond coatings. The diamond coating obtained in this way has a high adhesion to the cemented carbide substrate due to the enhanced interaction through the nanograined diamond interlayer.
