METHOD OF PREPARING WEAR-RESISTANT COMPOSITION

摘要

FIELD: chemistry. ^ SUBSTANCE: method is realised by cold pressing under specific pressure of 12.5 MPa with subsequent saturation in engine oil M-8B at temperature 150C for 24 hours and sintering at temperature 3705C. The invention enables to produce large group of cheap readily available materials with good structural and anti-frictional properties, capable of prolonged operation in self-lubrication mode in friction assemblies as friction bearings and movable sealants, including in cryogenic engineering. ^ EFFECT: method significantly increases wear-resistance and load capacity of articles made using the disclosed technique. ^ 2 cl, 4 tbl, 16 ex
