Изобретение относитс к электрохимическим методам анализа и предназначено дл анализа многофазных металлических сплавов.This invention relates to electrochemical analysis methods and is intended for the analysis of multi-phase metal alloys.
Известен способ определени толщины металлических покрытий, основанный на сн тии пол рограмм анодного растворени небольшого участка покрыти в прижимной двухэлектродной чейке С 1 1A known method for determining the thickness of metallic coatings is based on the removal of the polarogram of the anodic dissolution of a small portion of the coating in the presser C1 1 two-electrode cell.
Однако этот способ не дает возможности определ ть состав многофазных сплавов вследствие сложной интерпретации пол рограмм сплава.However, this method makes it impossible to determine the composition of multiphase alloys due to the complex interpretation of the alloying programs.
Наиболее близким к предлагаемому вл етс способ анализа сплавов, основанный на сн тии вольтамперных кривых анодного растворени небольшого участка поверхности сплава в прижимной двухэлектродной чейке и построении диаграмм состав - ток 2 .The closest to the proposed method is the analysis of alloys, based on the removal of the current-voltage curves of the anodic dissolution of a small portion of the alloy surface in the presser two-electrode cell and the construction of the current-to-current 2 diagrams.
Недостаток способа - существенна погр8шность в определении величины парциальных токов фаз сплава, которые раствор ютс при близких потенциалах.The disadvantage of the method is the substantial error in determining the magnitude of the partial currents of the phases of the alloy, which dissolve at close potentials.
Целью изобретени вл етс повышение точности анализа многофазных сплавов .The aim of the invention is to improve the accuracy of analysis of multiphase alloys.
. Поставленна цель достигаетс тем, что в известном способе анализа многрфазнь1х сплавов, включающем регистрацию вольтамперных кривых анодного растворени образца в прижимной двухэлектродной чейке, образец подвергают отжигу при температуре, на 2-10°С ниже темпераto туры фазового перехода, и закалке с последующим определением содержани компонентов сплава.. This goal is achieved by the fact that in a known method for analyzing multi-alloy alloys, including recording the current-voltage curves of anodic dissolution of a sample in a pressure two-electrode cell, the sample is annealed at a temperature 2-10 ° C below the temperature of the phase transition, and quenched, followed by determination of the content of components alloy.
На фиг. 1 представлены вольтампер15 ные кривые анодного растворени отожженных и закаленных (температура ЗОСГС и сплавов олово - медь); на фиг. 2 - диаграмма состав - ток.FIG. Figure 1 shows the voltampere curves for anodic dissolution of annealed and quenched (temperature AECS and tin-copper alloys); in fig. 2 - composition diagram - current.
