摘要：CoCrCuFeNi-TiO was prepared by arc melting of the pure elements and Ti2CO powder under an Ar atmosphere. Both CoCrCu-FeNi and CoCrCuFeNi-TiO alloys are composed of a face-centered cubic (fcc) solid solution, whereas the alloys of CoCrCuFeNi-TiO are basically composed of an fcc solid solution and TiO crystals. The microstructures of CoCrCuFeNi-TiO are identified as dendrite and interdendrite structures such as CoCrCuFeNi. The morphology of TiO is identified as an equiaxed crystal with a small amount of added Ti2CO. By increasing the amount of Ti2CO added, the TiO content was dramatically increased and part of the equiaxed crystals changed to a dendrite structure. A test of the oxidation resistance demonstrates that the oxidation resistance of CoCrCuFeNi-TiO is better than that of CoCr-CuFeNi. However, as the TiO content increases further, a corresponding decrease is observed in the oxidation resistance.
