Tooling materials science| Резюме: | In the work, the functional state of the surface of nanoscale diamond powders (NDP) was changed by annealing in a hydrogen atmosphere and an argon atmosphere. Annealing in such atmospheres affected the concentration of functional groups. As a result of annealing in argon, the level of adsorbed water and other unidentified impurities on the surface of NDP decreases, and after annealing in hydrogen, the number of all groups and impurities decreases even more significantly. After that, titanium and tungsten were sprayed onto the NDP by magnetron sputtering. As the results of the electronic observation of the deposited diamond powders showed, the quality of the deposition of the powders does not change depending on the functional cover of the NDPs. |
