Description
(54) ОПОСОБ ТРАВЛЕНИЯ МАГНИЕВЫХ СПЛАВСе(54) PASSING AGAINST MAGNESIUM SPLAVES
II
Изобретение относитс к химической обработке металлов и может найти применение в машиностроении и других област х .The invention relates to the chemical treatment of metals and may find application in mechanical engineering and other areas.
Известен способ химического травлени магниевых сплавов, включающий обра« ботку в растворах минеральных кислотThe known method of chemical etching of magnesium alloys, including processing in solutions of mineral acids
tl.tl.
Известен также способ травлени магниевых сплавов, -включающий обработку в растворах, содержащих ортофосфорную кислоту и ацетон или этиловый спирт, при , в течение 3 с t2 и З .There is also known a method of etching magnesium alloys, which includes processing in solutions containing orthophosphoric acid and acetone or ethyl alcohol, for 3 s t2 and H.
Наиболее близким к предлагаемому по те хнической сущности вл етс способ травлени магниевых сплавов, включающий последовательную обработку при комнатной температуре сначала в растворе, содержащем минеральные кислоты, спирт л аиетон, а затем п 5%-ном растворе азотной кислоты 4 .The closest to the proposed essence is the method of etching magnesium alloys, which includes sequential treatment at room temperature, first in a solution containing mineral acids, alcohol aeton, and then with a 5% solution of nitric acid 4.
Недостатком этих способов травлени вл етс то, что при травлении изделий из м шиевых гплавоп системы магнийиттрий (Moj- YV не обеспечиваетс качественное вы вление структуры сплава иэ-за образовани на поверхности шлифа непрозрачных, окисных пленок, которые могут быть удалены лшиь при повторном изготовлении шлифа методом шлифовани и полировани . Окисные пленки образуютс из-за большой химической активности иттри , вход щего в сплавы данной системы .The disadvantage of these methods of etching is that when etching products from microfiber systems of the magnesium nitrile system (Moj-YV, the structure of the alloy is not qualitatively detected because of the formation of opaque oxide films on the surface of the section, which can be removed when the section is re-manufactured by grinding and polishing. Oxide films are formed due to the high chemical activity of yttrium, which is part of the alloys of this system.

Цель изобретени - более полное и четкое вы вление структуры сплава системы магний-иттрий.The purpose of the invention is to more fully and clearly reveal the structure of the magnesium-yttrium alloy.
Поставленна пель достигаетс тем, что согласно способу, включающему поIS следовательную обработку при комнатной температуре сначала в растворе, содержащем минеральные кислоты, спирт и ацетон, а затем в 5%-ном растворе азотной кислоты, на первой стадии обрп)1гтки The delivered pellet is achieved in that according to the method, which, according to IS, is sequential treatment at room temperature, first in a solution containing mineral acids, alcohol and acetone, and then in a 5% solution of nitric acid, in the first stage)
