Description

Corrosion tests at 400 deg C in the air are carried out using specimens cut out of a Zr-2.5% Nb channel tube after its thermomechanical treatment consisting of cooling from a high-temperature range in inert gas environment, rolling and subsequent ageing at temperatures of 530-540 deg C (24 h). Then the specimens oxidized up to various stages are subjected to 3.8 MeV nitrogen ion implantation. It is revealed that the irradiation with nitrogen ions results as in the electrical conductivity of corrosion films which is several orders of magnitude greater than that in unirradiated films so in a decreased oxidation rate of the alloy. It is shown that the oxidation rate is greatly dependent of ion fluence and oxidation kinetics stage. Maximal effect is gained at a parabolis stage of oxidation

Abstract (Russian)

На образцах, вырезанных из канальной трубы сплава Zr-2.5% Nb после термомеханической обработки, состоящей из охлаждения из высокотемпературной области в инертном газе, прокатке и последующего старения при температуре 530-540 град С (24 ч), проведены коррозионные испытания в атмосфере воздуха при 400 град С. Затем образцы с различными стадиями окисления подвергали имплантации ионов азота с энергией 3.8 МэВ. Установлено, что облучение ионами азота повышает на несколько порядков электропроводность образовавшихся на сплаве коррозионных пленок и уменьшает скорость окисления сплава. Показано, что скорость окисления существенно зависит от флюенса ионов и кинетической стадии окисления. Максимальный эффект достигается на параболической стадии окисления
