The aim of the paper is the development of technological processes of acquisition of antifriction nanocarbon additives to automobile and transmission oils through high-power electrodischarge methods. For the first time technological processes of acquisition of antifriction nanocarbon additives to automobile and transmission oils through high-power electrodischarge methods are developed. It is proved that insertion of fullerenes screening the surfaces of the contact into the lubrication oil reduces total wear rate for the friction pair by 10% at nearly equal wear rate for both bodies of a contact pair. It is determined that this mechanism is connected with formation of high-hardness friction layers (8.7 GPa) on working surfaces of both bodies. At insertion of 0.1 to 0.15% nanocarbon additive into the oil, the stability of the friction pair will increase at decrease of mean values of friction coefficient by 18% and maximum temperature near the contact zone. The field of use – mechanical engineering. Product Description popup.authors Баклар В.Ю. Богуславський Л.З. Зубенко О.О. Малюшевська АюПю Петриченко Л.О. Петриченко С.В. Смалько А.О.
