Adhesion measurements of chemically vapor deposited and physically vapor deposited hard coatings on WCCo substrates
TL;DR: In this paper, the critical load in scratch adhesion is influenced by the hardness of the substrate and extraneously by the surface condition of the indenter and its coefficient of friction relative to the coating material.
Journal ArticleDOI
Adhesion and tribological properties of diamond films on various substrates
TL;DR: In this article, the adhesion of diamond films deposited by microwave plasma-enhanced CVD on various substrates can be quantitatively determined by an indentation method, and the friction behaviors of diamond-coated cemented carbides sliding against a brass ring were studied.
Journal ArticleDOI
Factors influencing the adhesion of diamond coatings on cutting tools
TL;DR: In this paper, diamond coatings have been applied on carbide tool inserts with a variation of substrate chemical composition and surface pre-treatment, and they have been characterized with respect to nucleation density, crystallinity, non-diamond material content and residual stresses.
Journal ArticleDOI
Behaviour of Co binder phase during diamond deposition on WCCo substrate
TL;DR: In this paper, the movement of the Co-rich binder phase and its interaction with growing diamond particles during deposition were investigated by repeated observations of the same site on a WC-Co substrate surface.
Journal ArticleDOI
Superhard coatings for metal cutting applications
TL;DR: In this paper, the authors present superhard coated tools, with an emphasis on diamond coated WC-Co tools, the corresponding deposition technologies and the foreseen metal cutting applications, and the precursors of these tools.
