Abstract
Diamond coatings chemically vapor deposited onto WC-Co cemented carbid es by use of specially developed barrier underlayers are described. Pr eliminary seeding the barrier underlayers with nano-grain diamond part icles by laser ablation allows obtaining fine-grained and uniform diam ond coatings. The diamond coatings obtained in this way have high adhe sion to the cemented carbide substrate due to enhanced interaction bet ween the underlayer, nano-grained diamond nuclei and gas phase employe d in their plasma-assisted chemical vapor deposition.
