Diamond coated tools and process for making |
摘要 |
A process for making a diamond-coated tool and the tool made thereby. The process includes a sintering step. In that step, the tool 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 prepared by the process includes a large grain substrate surface, and an high bond strength between the diamond coating and the substrate surface.
