The literary review of mold plastering casting structures applied to an alloying of a castings blanket from various alloys is carried out. On the basis of the studied literature the main conditions which observance is necessary for implementation alloying process are revealed. Are submitted data on plastering structures used for casting molds with various heat conductivity. Influence of such alloying on structure and property, as castings surfaces and on finished products properties is shown. As the presented data on a classical set of coverings components and on purpose of elements making them. The conditions necessary for an casting surface alloying by nanopowder of casting mold covering are given. A cases number is described when such alloying was applied and was successful. It is shown as thus castings surface properties changed.
