Diamond-coated tools and process for making |
摘要 |
A diamond-coated tool or wear part and a process for making them. The process includes a sintering step. In that step, a substrate is sintered in an atmosphere and for a time and at a temperature so that superficial, exaggerated grain growth is promoted that imparts a surface roughness which may serve as anchoring sites during a subsequent diamond coating step which is performed by a vapor deposition technique. The diamond-coated tool or wear part includes a large grain substrate surface, and a high bond strength between the diamond coating and the substrate surface. |
