Abstract

The article discusses the choice of powder charges and the properties of the powder composite material "iron-cast iron-glass", developed a charge for obtaining metal-glass material. The choice of the composition of the material "iron-cast ironglass" was substantiated by theoretical and experimental methods. With the theoretical substantiation of the composition of the charge, a model was built using FCM clustering of experimental data. In the experimental substantiation of the choice of the composition of the charge, the content of cast iron and glass, as well as the dispersion of their particles, were chosen as parameters for optimization. The microstructures, mechanical and tribotechnical properties of the materials ЖЧ10С2, ЖЧ20С4 and ЖЧ50С6, pressed at a pressure of 1000 MPa, sintered in a furnace in an endogas environment at a temperature of 1150 ° C, for 2 hours have been investigated. The dependences of the chemical composition, structure of the metal matrix and glass inclusions, as well as the physicomechanical and tribotechnical properties of sintered powder materials on the degree of dispersion, the content of cast iron and glass powders in the charge have been established. It was determined that the best complex of properties is possessed by materials containing 50 and 6 wt. %. Of cast iron and glass powders, respectively, with the dispersion of the first - 160 + 100 microns.

Keyphrases: charge, dispersion, iron-cast iron-glass, matrix, physical-mechanical, powder composite material, structure, tribotechnical properties
