Description

Influence of pH value of borate electrolytes on parameters of formation, thickness, electric strength, chemical and phase composition of anode-spark layers on aluminium alloy was studied by the methods of elementary and X-ray phase analyses. It was ascertained that the films containing up to 10 at.% of boron and carbon oxides were concentrated near the surface of anode layers. At a constant boron concentration increase in electrolyte pH from 6.5 to 10.2 results in growth of the coatings thickness and reduction of electric strength

Abstract (Russian)

С использованием методов элементного и рентгенофазового анализов изучено влияние величины рН боратных элеткролитов на параметры процесса формирования, толщину, электрическую прочность, химический и фазовый состав анодно-искровых слоев на сплаве алюминия. Установлено, что пленки, содержащие до 10 ат% оксидов бора и углерода, сконцентрированы у поверхности анодных слоев. При постоянной корнцентрации бора увеличение рН элеткролита от 6,5 до 10,2 приводит к росту толщтины покрытий и уменьшению элеткрической прочности
