COMPOSITE POWDER FILLER MANUFACTURING PROCESS

摘要

FIELD: composite materials. ^ SUBSTANCE: invention relates to a process of manufacturing composite powder filler for elastomer compositions designed for fabrication of articles operated under increased wear and dry friction conditions. Process resides in that titanium carbide particles are activated in a mechanochemical activator with mechanical energy supply intensity 1 to 5 kW/kg and dose 100 to 1000 kJ/kg in a medium selected from a series: air, nitrogen, argon, and vacuum at pressure from 10-2 to 1 atm until particles with average size not larger than 15 mum are obtained, after which high-pressure polyethylene is added to activator and titanium carbide particles are modified at mechanical energy supply intensity 0,05 to 0.5 kW/kg and dose 3 to 100 kJ/kg in a medium selected from a series: air, nitrogen, argon, and vacuum at pressure from 10-2 to 1 atm. ^ EFFECT: lowered coefficient of friction under dry friction conditions and reduced summary rate of wear of friction pair under hydroabrasive wear conditions. ^ 1 tbl
