Improvement of efficiency of use of liquid-glass mixtures Part 3. Nanodispersed materials

Abstract

The mechanisms of interaction of various ultradisperse substances with molding materials, as well as their influence on physical and technological properties, are considered. Examples of using of ultrafine nano-sized additives in foundry are given. The possibilities of increasing level of technological properties (initial strength, gas permeability and non-stick properties) of mixtures due to additives of UPC, which contributes the improvement of the surface quality of castings and to the reduction laboriousness of finishing operations are described.
