Description

(54) COMPOSITION FOR REMOVAL OF REASONS

,one

 The invention relates to chemical removal of burrs upon exposure to ultrasound; Ka from the surface of iron-nickel parts & ee alloys (permallo) after me aniche-Ikoft processing. 5

G Known working fluids for chemical JKoro removal of burrs when exposed to ultrasound based on the aqueous solution ® perdrol. with organic compounds, I To remove the burrs from the electroplating technical I of alloys, an aqueous solution of per. | hydrol is used, in which citric acid is introduced; that However, in this working fluid;.: The nickel-nickel alloy is not processed. Known solution for ultrasound with a hundred; ig deburring parts made by:. from permallo with a nickel content of 48-80%, including an organic compound (spruce acid), perhydrol and water, as diluent (see aut. St. USSR №208821) in Cl. Zld, 48).

The purpose of the inventions is to create such (positions for chemical removal of the burr) | when exposed to ultrasound from the surface; children made from (bilestone: goSplav (79 NM permallo)), which ensured an increase in the class quality to the treated surface , compared with the known solutions of Mk.; i To do this, the following solution was introduced into the known solution in organic quality, at j, the ratio between the components (% by weight,% Gyushch) hydroxylamine perhydrol hydrochloride .6

Hydroxylamine Solvent contains Avium, lean, chlorine ions and an amino group that is a corrosion inhibitor that results; to the optimal etching rate of all kSN & nantov of an alloy at ultrasound with oh processing.

To prepare the proposed composition, the necessary amount of water is dissolved in water.

the amount of hydroxypamine hydrochloride, immediately before the treatment, perhydrol is added in the required amount.
