This paper reviews studies undertaken on diamond cutting tools, with particular regard to the characteristics and performance of diamond/metal interfaces. The affinity of carbon to metals, as well as the wettability of diamond by molten metals and the advantage of using coated diamonds under certain cutting conditions, are described. The choice...

The wetting of Ni-Hf and Ni-Cr-Hf alloys on sapphire has been studied in this work. Sapphire represents a "simple" and ideal case adopted for better understanding the basic phenomena involved in liquid/solid contact during casting of Ni-based superalloys. Wettability tests were performed by means of the sessile drop method at 1500 °C; moreover,...

The isothermal wetting, spreading behaviour and interfacial reactivity of NiAl1, NiAl10 and NiAl25 alloys (1, 10, 25 at% Al, respectively) on monocrystalline alumina (sapphire) and polycrystalline zirconia oxides stabilized with MgO (stoichiometric and non-stoichiometric ones) were studied by means of the sessile drop method at 1500 °C in...
