High strength steel back of pom composites (FZF - 8) consists of the steel substrate, the spherical bronze powder, bronze wire spiral, superficial plastic (modified polyformaldehyde) composed of four layers of composite material.

Spherical bronze powder and bronze wire spiral through high heat sintering and the steel substrate firmly together, for the surface layer of plastic and steel substrate conjointly intermediaries. Copper screw half buried in the spherical copper powder, the other half into the surface of plastic, at the same time, the surface layer of plastic to infiltrate into the gap of spherical copper powder.

FZF - 8 material but make it slide, also can make composite sheet, roll sleeve is made.

FZF - 8 material combines the advantages of metal and plastic, both has the high bearing capacity, good dimensional stability, excellent antifriction sex again at the same time, friction resistance, compatibility and adaptability. Is a kind of new sliding bearing materials performance is very outstanding, has the very broad application prospects.

1, high bearing capacity

FZF - 8 material is three layer steel back of pom composites (domestic brands of FZ - 2, 2) SF - improved and enhanced. Compared with three layers of composite material, FZF - 8 materials due to the combination of surface layer of plastic and steel substrate with higher fastness, so the material has higher bearing capacity.

2, the friction and wear performance

FZF - 8 materials work surface is modified polyformaldehyde, has the very good self-lubricating properties, especially when the oil molecules for poly formaldehyde adsorption capacity to 20% larger than for metal materials, therefore, FZF - 8 material has very excellent characteristics of boundary lubrication, boundary lubrication film bearing capacity is very high, under the higher load, have a small amount of oil, the friction coefficient is lower than 0.05.
