The paper describes the technology for producing silver electrochemical coatings containing multi-walled carbon nanotubes (MWCNTs). The MWCNT effect on the roughness, structure and tribological properties of silver coatings obtained with the addition of the nanotubes to an electrolyte in the low concentration range (0 to 80 mg/L). An increase in the microhardness and a decrease in the coefficient of friction were found for the modified coatings at the MWCNTs concentrations in the electrolyte of 40 and 60 mg/L, respectively.
The questions of application of nanomaterials in mechanical engineering are considered. Concept of electrochemical processing products in mechanical engineering with the use of a solid nanodisperse phase is defined. The characteristics and methods of application in the processes of electrodeposition of carbon nanomaterials are determined. The results of experimental investigations of electrolytic chrome plating with multi-walled carbon nanotubes of the "Taunit" series are presented.
The paper presents the results of studying the nickel electroplating process in the presence of nanodiamond additives. It shows that the use of detonation nanodiamonds (DND) and diamond explosive charge (DC) obtained by explosion of tetryl (N-methyl-2,4,6-trinitrophenylnitramine) can significantly improve the physicochemical properties of nickel platings: increase the microhardness up to 60 % (up to 448 kgf/mm2 – 4393 MPa), obtain a non-porous nickel plaiting and reduce wear up to 28 times. The most effective was the use of non-expensive nanodiamonds, but cheap diamond charge obtained by the explosion of tetrile.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
