Abstract
Solid-phase mechanochemical methods for the synthesis of new materials, metal-fluoropolymer and metal-ceramics-fluoropolymer composites have been developed. Composite materials possessing high electric conductivity, low friction coefficient and mechanical attrition resistance were synthesized from W-Cu, WC-Cu, and Cu-TiB2 and ultrafine polytetrafluoroethylene (UPTFE) systems. It is demonstrated that thermal stability of mechanically processed pure UPTFE differs from that of the PTFE component of mechanocomposites and depends on the nature of the main component of the composite.
