Metal Science and Treatment of Metals| Резюме: | The complex saturation of the heat-resistant alloy HN55VMTKY was carried out in a powder mixture of metals Ti (15% by weight); Al (15% by weight); Cr (25% by weight); Al2O3 (40% by weight); NH4Cl (5% by weight) in flashing containers at a temperature of 1050°C for 4 hours. The samples with coatings were investigated by methods of modern physical material science. Under the accepted conditions of titanium-alumochromination, a multilayer coating of Al2O3, TiNiAl (g-phase) AlNi2Ti (Hustler phase) is formed on the surface of the alloy ХН55ВМТКЮ. The concentration of Ti, Al, Cr on the outside of the coating is 50.0, respectively; 17.5; 27.5% by weight. As a result of titanium aluminum chromium alloys ХН55ВМТКЮ at a temperature of 1000 °С increase in 10,6 times in comparison with the initial. The maximum microhardness was found for the columnar crystal zone – 9.8-10.8 GPa. |
