摘要
Isothermal oxidation of nickel alloy containing (wt %) Ni (main), Cr 25.1, Co 26.3, W 10.3, Ti 1.9, and Mo 1.2 was studied at temperatures of 1100 and 1200A degrees C in air. The disperse particles of titanium nitride found to increase alloy heat-resistance. The aluminosiliconization of alloy strengthened by nitride particles at a depth of 45-50 mu m decreases the oxidation rate of alloy strengthened by disperse particles of titanium nitride at temperatures of 1100 and 1200A degrees C.
