Anodic dissolution of two heat-resistant chrome-nickel alloys containing 12 % (weight) of tungsten and 8 % of tungsten with 6 % rhenium in 2 M NaNO3 solution was investigated using rotating disk electrode at current density up to 30 A/cm2. It is shown that anodic dissolution of these alloys occurs in transpassive region of potentials with transition of its components in solution in forms with highest oxidation level. The various mechanisms of alloy dissolution are offered, including: disintegration of hardening phase; chemical oxidation of intermediates by solution components; electrochemical formation of superficial oxide layers. Some modes of electrochemical machining of these alloys with better parameters are offered. |
