METHOD OF PRODUCING HIGH-TEMPERATURE COMPOSITE ANTIFRICTION MATERIAL Russian patent published in 2019 - IPC B22F3/14 C22C19/03 C22C1/10 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to production of article from high-temperature composite antifriction material. Method involves preparation of powdery components of the initial mixture, grinding to preset particle size, molding and sintering. Initial mixture contains nickel, molybdenum, copper and molybdenum disulphide. Preparing the powdered components of the initial mixture is carried out by mechanical activation in a planetary mill to an average particle size of not more than 100 nm. Formation of obtained mixture is performed by hot pressing in induction vacuum plant in graphite molds with stepped rise of temperature and stage-wise holding.

EFFECT: higher mechanical efficiency of antifriction material under conditions of high-intensity mechanical effects of friction forces of rolling, rotation and high temperatures.
