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 has been studied at 1100 and 1200A degrees C in air. It has been found that disperse particles of titanium nitride increase the alloy heat-resistance. Alumosiliconizing of the alloy strengthened by nitride particles to a depth of 45-50 mu m decreases by an order of magnitude the oxidation rate of alloy strengthened by disperse particles of titanium nitride at 1100 and 1200A degrees C.
