Изобретение относитс к разработке способов фазового анализа сплавов на основе титана , в частности дл выделени у-фазы в а- и (а+р)-сплавах.The invention relates to the development of methods for the phase analysis of alloys based on titanium, in particular for the separation of the γ phase in a- and (a + p) -alloys.
Известен способ фазового анализа сплавов на основе титана, заключающийс в анодном электролитическом растворении сплава в электролите , содержащем:The method of phase analysis of titanium-based alloys is known, which consists in anodic electrolytic dissolution of the alloy in the electrolyte, containing:
Аскорбинова или сульфосалицилова кислота, г3Ascorbic or sulfosalicylic acid, g3
Серна кислота (плотностьSulfuric acid (density
1,84), мл151.84) ml15
Метанол, мл1000Methanol ml1000
при плотности анодного тока 0,05 а/см с последующей промывкой отделенного анодного осадка в спирте.at anode current density of 0.05 A / cm, followed by washing the separated anodic precipitate in alcohol.
Цель изобретени - выделение гидридной фазы в а- и (а+р)-сплавах на основе титана. Предлагаемый способ фазового анализа сплавов на основе титана отличаетс от известного тем, что анодное электролитическое растворение основы производитс в электролите, содержащем:The purpose of the invention is to isolate the hydride phase in titanium-based a- and (a + p) -alloys. The proposed phase analysis method for titanium-based alloys is different from the fact that anodic electrolytic dissolution of the substrate is carried out in an electrolyte containing:
Кислота, выбранна из группы, включающей сульфосалициловую , лимонную, салициловую кислоты, г 1-25 Серна кислота (олеум)Acid selected from the group including sulfosalicylic, citric, salicylic acid, g 1-25 Sulfuric acid (oleum)
(плотность 1,86), г2-20(density 1.86), g2-20
Метанол, мл1000Methanol ml1000
при плотности тока 0,01-0,20 а/дм и температуре электролита от -15 до -1-20°С.at a current density of 0.01-0.20 a / dm and the temperature of the electrolyte from -15 to -1-20 ° C.
Промывка и коагул ци отделенного анодного осадка осуществл етс в этаноле, содержащем перхлорат натри в количестве 0,1-0,5 г/л.Washing and coagulation of the separated anodic precipitate is carried out in ethanol containing sodium perchlorate in an amount of 0.1-0.5 g / l.
Введение в известный электролит олеума (серной кислоты, содержащей в свободном виде серный ангидрид) и применение дл промывки отделенного анодного осадка этанольного раствора перхлората натри позволило изолировать гидридную фазу в а- и (а+р)титановых сплавах, содержащих водород в количестве от 0,004% и выше, и получить анодные осадки, не загр зненные пассивированными частицами и компонентами электролита.The introduction of oleum (sulfuric acid containing free sulfuric anhydride) into the known electrolyte and the use of an ethanolic solution of sodium perchlorate for washing the separated anodic precipitate made it possible to isolate the hydride phase in a- and (a + p) titanium alloys containing from 0.004% hydrogen above and obtain anodic sediments not contaminated with passivated particles and electrolyte components.
