A method for removing 2 impurities from the melt has been developed.??The results of corrosion tests performed on samples of nickel-based alloys in a setup with natural circulation with maximum melt temperature up to 700?C and redox potential of the system 1.25n1.33 V relative to a beryllium comparison electrode are presented. It is shown that deep removal of oxidizing impurities from the melt and maintaining a low redox potential give slow uniform corrosion (less than 5µm/yr) of Kh80MTYu and KhN80M-VI samples. After the tests were completed,none of the alloys studied exhibited any tendency toward intercrystallite absorption.
