The new diamond-coated carbide cutting tools

Abstract CVD diamond sheet (thick film, > 250 μm) tools have been available for several years. However, commercially useful thin-film (

Theory and practice in diamond coated metal-cutting tools

Abstract The development of low pressure deposition of continuous, high quality, diamond film was a major breakthrough in materials science that has allowed an economical use of diamond as an engineering material. It has also precipitated similar research in other superhard materials, such as cBN, C3N4 and superlattice nanolayer structures. This paper will highlight basic and applied aspects of diamond coatings, and present a technology perspective on the preparation of diamond-coated tools. Some of the key factors affecting the adhesion of diamond to cemented carbide will be discussed. The performance characteristics of the diamond tools and the anticipated applications will be reviewed.

Superhard coatings for metal cutting applications

Abstract An effective metal cutting tool is usually a combination of a hard coating and a tough substrate. The successful deposition of diamond outside its thermodynamic stability range has stimulated the development of a new class of cutting tools: those with diamond coated inserts at any desired style and edge geometry. The successful implementation of diamond coatings also expedited similar research in the deposition of cubic boron nitride. This paper presents superhard coated tools, with an emphasis on diamond coated WC-Co tools, the corresponding deposition technologies and the foreseen metal cutting applications.
