| Research Abstract |
For Mo-Cr nitride sintered compacts prepared by pulse electric current sintering of mixed powder of Mo_2N and CrN, the oxidation behavior in air and corrosion behavior in boiling sulfuric acid were investigated. Mo-Cr nitride sintered compacts exhibited superior oxidation resistance up to 1000℃. The corrosion rate of Mo-Cr nitride sintered compacts in boiling 75 wt% sulfuric acid was less than 0.05 mm/y.
