“…In order to deposit molybdenum-containing coatings on the diamond surface, the molten salt method [ 10 , 11 ], magnetron sputtering [ 12 ], chemical vapor deposition [ 13 ], or vacuum micro-vapor deposition can be used [ 14 ]. Recently, a new method for obtaining coatings on powder particles (crystals) based on annealing of the powder mixtures (the substrate mixed with a coating precursor) in a spark plasma sintering (SPS) facility (coating of diamond by Ti) [ 15 ] or a hot press (HP) (coating of diamond by W) [ 16 ] has been proposed. This approach is characterized by a high efficiency and a relative simplicity of the technological process.…”

“…Owing to the intrinsic differences between the {100} and {111} facets, the interactions of these facets with an external reactant may be expected to proceed differently. The effect of selective deposition of coatings on certain facets of the diamond crystals has been observed for silver [ 19 ], tungsten [ 16 ], and molybdenum [ 14 ]. As suggested in [ 16 ], oxides present on the surface of metallic particles can play a significant role in the process of the coating formation, if they are the volatile and enable the gas-phase transport of the coating precursor material to the diamond surface.…”

“…Metallic W-containing coatings are applied to the surface of diamond microcrystals by hot pressing, with the use of WO 3 as a metal source [3]. The coatings formed on the diamond surface react with WO 3 powder during hot pressing at elevated temperature.…”

“…The average coverage of diamond grains, for exam ple, by boron oxide (B 2 O 3 ) is 5.64% (the B 2 O 3 density is 2.55 g/cm 3 , the diamond density is 3.56 g/cm 3 ).…”
