Abstract
Determination of the composition of materials and methods of obtaining products from them for seals of pumping units. A powder composite material “iron-cast iron” is proposed for the manufacture of seals used in friction units of pumps. The necessity of choosing cast iron powder for obtaining compositions of this type is shown. As a powder of cast iron,a special gray cast iron with interdendritic point graphite is proposed. The cremical composition, properties of gray cast iron and the properties of powder compositions obtained by cold pressing and sintering from five charge compositions. It is noted that due to the fact that the seals must have special tightness, they must be subjected to subsequent compaction.
Keywords: iron-castiron, composition, interdendritic point graphite, pearlite, chemical composition, strength, powder charge.
