Abstract

The article discusses the possibility of obtaining a composite coating on the surface of iron castings in the process of melt molding. As the composite powder mixture to the mold surface spreads used alloy powders and nickel-based low-alloyed white cast iron. Particle size distribution of these powders meet the following fractions: + 50-63; + 63-100; + 100-160; + 160-200; + 200-315 μm. It is established that a decrease in the thickness of the powder coating to 3-5mm casting of cast iron into a mold with powder spread at 1420-1440°C and the dispersion of the powder particles 50... 100 μm contribute to the formation of quality castings with a composite coating low-alloyed chrome-nickel white cast iron - gray cast iron and "nickel alloy CrNi80Si2B2 - gray cast iron". The increase in the casting temperature of cast iron from 1340°C to 1440°C increases the impregnation depth of the spread on the basis of the powder from low-alloyed chrome-nickel white cast iron and CrNi80Si2B2 by 3-4 mm. It is found that by forming the composite coating on the surface of the mechanical properties and corrosion resistance of the castings are significantly increased compared to bare casting for the same composition. It has been established that the σB and HB of the material of the "CrNi80Si2B2 - gray cast iron" composite coating in comparison with cast iron increases in 1.86-1.94 and 1.20-1.24 times, wear resistance - by 1.5 times, and corrosion resistance in 43 times; for the material "low-alloyed chrome-nickel white cast iron - gray cast iron" these figures improve 1.44 times and 2.55 times, wear resistance 5.6 times and corrosion resistance 4.25 times. Optimum technological parameters for manufacturing of cast-iron castings with a composite coating "powder nickel alloy CrNi80Si2B2 - gray cast iron Class 20" with the raised wear resistance, corrosion resistance and durability are recommended. Technological processes have been developed for the manufacture of castings with a composite coating - type bushings and parts of cast-iron valves.
