UDC 621.744.37: 669.13 Research of  properties nonstick coatings for cast iron based on chemically and mechanically activated graphite

The interaction of iron with cryptocrystalline graphite treated in different ways, by a drop in the rest of the universal vacuum system "drop" (JSC RI "reg", Russia). It is found that the graphite processed in various ways, has a contact angle greater than the natural. Antipenetration tested coatings on the basis of the test cryptocrystalline graphite. It was revealed that the casting produced using antiburning cover-treated in various ways cryptocrystalline graphite, have the best technological and operational properties. Keywords: cryptocrystalline graphite, graphite is mechanically activated, nonstick coatings for cast iron.

UDC 666.7  INFLUENCE OF DIFFERENCE decomposition temperature of the starting compounds to magnesium oxide and aluminum on the intensity of the reaction of the spinel

The aim of this work is to study the possibility of synthesis of aluminum-magnesium spinel MgAl2O4 at relatively low temperatures of powders of aluminum hydroxide Al (OH) 3 and magnesium hydroxycarbonate Mg4 (CO3) 3 (OH) 24H2O. The studies found that the intensity of the spinel reaction at relatively low temperatures the higher the closer to the decomposition temperature of oxides of magnesium and aluminum source compounds. The scheme of the thermal decomposition of a mixture of magnesium hydroxycarbonate and aluminum hydroxide. From the results of studies suggest that the synthesis of complex oxides of metals from their compounds to intensify solid-phase reactions with sufficiently complete conversion of oxides into final products at relatively low temperatures is necessary to take the initial metal compounds having the same or close to the decomposition temperature of oxides metals. Keywords: magnesium aluminum spinel , aluminum hydroxide, magnesium hydroxycarbonate, decomposition temperature, gibbsite, degree of spinel formation, calcination, radiograph.
