Effect of Nanocarbon Additions on Graphitization and Tribological Properties of Gray Cast Iron

Resumo

The expediency of using nanostructured carbon materials (graphene, fullerene black) as effective additives to a cast iron modifier is substantiated. Experimental results for preparation of high quality iron castings with nanocarbon additions in the presence of a combined modifier are confirmed by improvement of cast iron structural and tribological properties. The promising nature of using fullerene black (FB) as a comparatively cheap by-product of fullerene nanotechnology exhibiting improved tribological properties is demonstrated. The mechanism of graphitization of cast iron modified with FB-additive is revealed on the basis of existing studies and results of research in the field of nanomodification.
