Abstract
In work are submitted data of casting mold coverings with nanopowders application for molding lead bronze. Influence of a structure of used protective - separating coating of a foundry core on a microstructure of castings was investigated. For experimental work following coverings (the patent No 2297300) a mix dioxide zirconium nanopowder with industrial oil, and the same structure, but already on a basis on oxide aluminum nanopowder have been chosen. It is shown that these coverings application leads to decrease in quantity of surface defects, the roughness of a cast surface decreases. At the same time penetration of particles of a powder from a foundry covering in casting doesn't occur.
