Structure Phase

The structure, phase composition and tribotechnical properties of the impeller casting for oil and centrifugal pumps made from high-chromium steel 20Cr15Mn3, obtained by the technology of precise casting, were studied. It was concluded that impeller casting made from high-chromium steel 20Cr15Mn3, obtained by the technology of exact casting of Sol-Gel in ceramic molds, had improved properties and can serve as a replacement for the traditionally used material – cast iron.

Spraying Process

The study of the structural-phase state and anticorrosive properties in a 10 % aqueous solution of NaCl of hypersonic metallization coatings made of 08Mn2Si, 40Cr13, 09Cr19Ni9Ti steels, A199,3 aluminum and pseudo-alloys Fe—Al and Fe—Ni—Cr has been carried out. It has been established that hypersonic metallization coatings made of A199,3 aluminum and pseudo-alloys Fe—Al and Fe—Ni—Cr have the highest corrosion resistance. High corrosion resistance of the coating made of pseudo-alloy Fe—Al is achieved due to the enveloping of steel particles with aluminum during the spraying process, as well as due to the formation of a film of aluminum oxides on the surface of aluminum interlayers and aluminum-alloyed iron interlayers. High corrosion resistance of coatings made of high-chromium steels is due to their alloying with chromium and nickel.

Thermal Coating

Comparative study of the structural-phase state and tribotechnical properties of gas-thermal coatings from steels 08Mn2Si, 40Cr13, 95Cr18, as well as the pseudoalloys 08Mn2Si + bronze SiMn3-1, 08Mn2Si + AlSi12, 40Cr13 + bronze SiMn3-1, 95Cr18 + brass 63Cu, 95Cr18 + Al99.9 is carried out. It is shown that gas-thermal coating made of 95Cr18 steel has the highest wear resistance under conditions of dry friction due to the occurrence of intense martensitic γ → α transformation in its surface layers during friction. It is established that the pseudoalloys 08Mn2Si + bronze SiMn3-1 and 08Mn2Si + AlSi12 have higher wear resistance compared to the coating made of 08Mn2Si steel, which is associated with low content of iron oxides in the coatings of falsely alloys. For coatings from pseudoalloys 95Cr18 + brass 63Cu and 95Cr18 + Al99.9 lower wear resistance is characteristic in comparison with coating of 95Cr18 steel. The reduced wear resistance of pseudoalloys based on 95Cr18 steel is associated with their relatively low strength characteristics compared to steel coating of wire tool steel.
