Изобретение относитс к области коррозионных испытаний материалов, а именно к способам определени коррозионной стойкости сварных соединений циркониевых сплавов.The invention relates to the field of corrosion testing of materials, and specifically to methods for determining the corrosion resistance of welded joints of zirconium alloys.
Известен снособ коррозионных испытаний сплавов циркони , заключающийс в том, что испытываемый образец помещают в электролит , нагревают и пол ризуют нутем наложени анодного тока. Однако известный способ не позвол ет получить быструю информацию о коррозионной стойкости сварных соединений .The corrosion test of zirconium alloys is known, in that the test sample is placed in an electrolyte, heated and polarized by applying an anodic current. However, the known method does not provide quick information about the corrosion resistance of welded joints.
Предлагаемый способ отличаетс от известного тем, что пол ризацию провод т в интервале потенциалов, выбираемом из услови сохранени пассивного состо ни основным металлом образца, выдерживают образец в этом интервале потенциалов, и о коррозионных свойствах сварного соединени суд т по изменению цвета окисной пленки. Это позвол ет провести ускоренную оценку коррозионной стойкости сварных соединений.The proposed method differs from that known in that the polarization is carried out in the potential range selected from the condition that the base metal of the sample is in a passive state, the sample is kept in this potential range, and the corrosion properties of the welded joint are judged by the color change of the oxide film. This allows an accelerated assessment of the corrosion resistance of welded joints.
По предлагаемому снособу испытываемый образец сварного соединени помещают в электролит, в котором основной металл сварного соединени заведомо стоек, нагревают до температуры, близкой к температуре, приAccording to the proposed procedure, a test specimen of a welded joint is placed in an electrolyte, in which the base metal of the welded joint is obviously racks, heated to a temperature close to the temperature at
которой эксплуатируетс сплав, анодно пол ризуют до потенциала несколько менее ноложительного , чем нотенциал выхода из пассивного состо ни основного металла в этом электролите, выдерживают образец при этом потенциале и о сравнительной стойкости отдельных участков соединени суд т по качеству образовавшихс на этих участках окисных пленок.by which the alloy is exploited, anodically polarized to a potential somewhat less positive than the output potential of the passive state of the base metal in this electrolyte, the sample is maintained at this potential and the comparative stability of individual sections of the compound is judged by the quality of the oxide films formed on these sections.
Предмет изобретени Subject invention
Способ коррозионных испытаний сплавов циркони , заключающийс в том, что испытываемый образец помещают в электролит, нагревают и нол ризуют, отличающийс тем, что, с целью ускоренной оценки коррозионной стойкости сварных соединений сплавов, пол ризацию нровод т в интервале потенциалов , выбираемом из услови сохранени пассивного состо ни основным металлом образца , выдерживают образец в этом интервале потенциалов и о коррозионных свойствах, сварного соединени суд т по изменению цвета окисной пленки.The method of corrosion testing of zirconium alloys, which consists in placing the test sample in an electrolyte, heating and zeroing it, characterized in that, in order to accelerate the corrosion resistance of the welded joints of the alloys, polarization is carried out in the potential range chosen from the condition of the passive the state of the base metal of the sample, the sample is kept in this range of potentials and the corrosion properties of the welded joint are judged by the change in color of the oxide film.
