Аннотация:Diamond coatings chemically vapor deposited onto WC-Co cemented carbides by use of specially developed barrier underlayers are described. Preliminary seeding the barrier underlayers with nano-grain diamond particles by laser ablation allows obtaining fine-grained and uniform diamond coatings. The diamond coatings obtained in this way have high adhesion to the cemented carbide substrate due to enhanced interaction between the underlayer, nano-grained diamond nuclei and gas phase employed in their plasma-assisted chemical vapor deposition.
