Preparation of wear-resistant chromium coatings using nanodiamonds of different nature

The processes of electrodeposition of chromium in the presence of nanodiamonds obtained by detonation and static syntheses were compared. It is shown that, in both cases, the microhardness of chromium-diamond coatings increases, with a higher increase observed for nanodiamonds obtained by detonation synthesis. It is established that the totality of properties of nanodiamonds of detonation synthesis make these materials more predominant compared to classical diamonds of the same size.
