Theory and practice in diamond coated metal-cutting tools

Progress in abrasive fluidized bed machining

“…(i) Poor adhesion of diamond coatings to WC-Co substrates is observed due to the deleterious effects of the binder phase (solid solution of W and C in Co), where Co is a good catalyst for the formation of interfacial graphite (Haubner et al, 1993;Nesladek et al, 1995;Inspektor et al, 1997). (ii) Low nucleation density occurs due to carbon dissolution in the binder phase (Zhang and Zhou, 1997).…”

Wear performances and mechanisms of ultrahard polycrystalline diamond composite material grinded against granite

“…Chemical vapor deposition (CVD) diamond is one of the ideal superhard materials for its unique chemical and physical characteristics, such as high hardness and wear resistance, good thermal conductivity, low friction, thermal expansion coefficient, and so on. Although CVD diamond is much harder than ordinary PCD, its application is limited by its weak fracture toughness [5,6].…”

Chemical vapour deposition of diamond films onto tungsten carbide dental burs

“…Fig. 8 shows that inorganic fillers from acrylic teeth adhered to the cutting tool surface in localised areas when increased rate of abrasion was used [14]. Fig.…”
