Description
Изобретение относится к области машиностроения, в частности к размерной электрохимической обработке монелевых сплавов на медноникелевой основе с повышенным содержанием кремния.The invention relates to the field of engineering, in particular to dimensional electrochemical processing of monel alloys on a copper-nickel basis with a high content of silicon.
Известны электролиты для обработки сплавов на шлицевой основе, представляющие собой водные растворы хлористых иазотнокислых солей щелочных металловKnown electrolytes for processing alloys on a spline basis, which are aqueous solutions of chloride and nitric salts of alkali metals
При обработке в известном электролите монелевых сплавов вследствие неодинаковых скоростей анодного расвсрёния компонентов сплава (никеля, меди, кремния) качество получаемой поверхности низкое.When processing monel alloys in a known electrolyte, due to the unequal speeds of the anodic disintegration of the alloy components (nickel, copper, silicon), the quality of the surface obtained is low.
Целью данного изобретения является повышение качества обрабатываемой поверхности.The aim of this invention is to improve the quality of the processed surface.
Поставленная цель достигается тем, что в состав электролита на основе азот*: нокислого натрия и хлористого натрия дополнительно введены фтористый натрий и азотнокислый аммоний, причем компоненты взяты в следующих соотношениях, вес- %:This goal is achieved by the fact that sodium fluoride and ammonium nitrate are additionally introduced into the composition of the electrolyte based on nitrogen *: sodium nitrate and sodium chloride, and the components are taken in the following proportions, wt%:
А.зотнокислый /натрий . 8—10A. Acid / sodium. 8-10
Хлористый натрий 5-6Sodium Chloride 5-6
Фтористый натрий 0,6-0,8Sodium fluoride 0.6-0.8
Азотнокислый аммоний 1,0-2,0Ammonium nitrate 1.0-2.0
Вода ОстальноеWater Else
Введение фтористого натрия придает электролиту способность растворять кремний, входящий в состав монелевых сплавов, а наличие азотнокислого аммониз позволяет получить равномерно-блестящую обработанную поверхность.The introduction of sodium fluoride gives the electrolyte the ability to dissolve silicon, which is part of monel alloys, and the presence of ammonium nitrate allows you to get a uniformly shiny treated surface.
Эффективность электролита подтверждается сравнительными испытаниями.The efficiency of the electrolyte is confirmed by comparative tests.
