КОМПОЗИЦИОННЫЙ МАТЕРИАЛ ДЛЯ ТРИБОТЕХНИЧЕСКИХ ПОКРЫТИЙ

摘要

FIELD: polymeric materials technology. SUBSTANCE: composition material based on polyamide matrix and carbon filling agent comprises as polyamide matrix the modified polyamide powder-like product of cryogenic grinding thermomechanically combined mixture of polyamide-6 and polyethylene taken in the ratio = 10:(1-0.1) and as carbon filling agent mixture of carbon components of graphite-like and diamond-like modification and carbon-graphite fiber taken in the ratio = (1:1:20)-(1:1:40), respectively. Invention can be used in machine engineering for making tribotechnical coatings in friction units exploited both with lubricant and without lubricant. Invention provides the enhancement of tribotechnical indices of coatings based on polyamides and providing high level of adhesion indices of coatings on non- -modified metals. EFFECT: improved and valuable properties of composition material. 2 tbl
