Abstract

In order to improve the performance of diamond coated cutting tools, we surveyed correlation between the endurance of coatings and the adhesive fracture toughness of chemically vapor-deposited diamond. We performed the cutting tests of tools with diamond coatings deposited under several conditions of methane concentration. The obtained data of their endurance showed a strong correlation to the complex behavior of adhesive toughness with respect to the methane concentration already reported by the authors. Durability of diamond coating could be enhanced by three times with an optimum control of methane concentration in the deposition process.
