Description

Дл  Эффективного воздействи  на аустенитную сталь известных травильных растворов, содержащих азотную и сол ную кислоты и ион фтора, требуетс  их нагревание, что св зано с выделением вредных паров или газов.To effectively expose austenitic steel to known etching solutions containing nitric and hydrochloric acids and fluorine ions, they need to be heated, which is associated with the release of harmful vapors or gases.

Описываемый раствор дл  травлени  аустенитных сталей, легированных титаном, может примен тьс  без подогрева, что улучшает услови  труда обслуживающего персонала.The described solution for etching austenitic steels alloyed with titanium can be used without preheating, which improves the working conditions of the staff.

Достигаетс  это изменением состава травильного раствора и снижением содержани  в нем сол ной кислоты.This is achieved by changing the composition of the pickling solution and reducing its hydrochloric acid content.

Раствор содержит (в г/л): азотной кислоты 350-400 сол ной кислоты 28-35 плавиковой кислоты 28-35, вода - остальноеThe solution contains (in g / l): nitric acid 350-400 hydrochloric acid 28-35 hydrofluoric acid 28-35, water - the rest

Травление ведут при комнатной температуре.Etching is carried out at room temperature.

При работе в услови х низких температур, например при - 10° до -25°, содержание в растворе сол ной кислоты увеличивают вдвое дл  повышени  активности травильного раствора.When operating at low temperatures, for example at -10 ° to -25 °, the content in hydrochloric acid solution is doubled to increase the activity of the pickling solution.

Продолжительность травлени  зависит от толщины сло  окалины на поверхности обрабатываемых деталей и температуры раствора. При комнатной температуре продолжительность обработки должна составл ть от 30 до 90 мин.The duration of etching depends on the thickness of the scale on the surface of the workpiece and the temperature of the solution. At room temperature, the treatment time should be between 30 and 90 minutes.

Поверхность металла после травлени  получаетс  чистой, без коррозионных дефектов.After etching, the metal surface is clean and free from corrosion.

Предмет изобретени Subject invention

1.Раствор дл  травлени  аустенитных сталей, легированных титаном , содержащий азотную и сол ную кислоты и ион фтора, отличающийс  тем, что, с целью новышени  травильных свойств и улучшени  условий труда, в его состав вход т компоненты в следующем соотношении (в г/л):1. The etching solution for austenitic steels alloyed with titanium, containing nitric and hydrochloric acids and fluorine ion, characterized in that, in order to improve the etching properties and improve working conditions, its components include the following ratio ):

азотна  кислота 350-400 сол на  кислота 28-35 плавикова  кислота 28-35 водаостальноеnitric acid 350-400 hydrochloric acid 28-35 hydrofluoric acid 28-35 water rest

2.Раствор по н. 1, отличающийс  тем, что, с целью цовышени  его активности при работе в услови х низких температур, наиример при -10 до -25°, содержание в нем сол ной кислоты увеличивают вдвое.2. Solution in n. 1, characterized in that, in order to increase its activity when operating in low temperature conditions, at about -10 to -25 ° C, its hydrochloric acid content is doubled.
