FIELD: method and composition for selective removal of iron solvent oxide from surface of titanium parts without damaging them.
SUBSTANCE: method comprises steps of adding to distillation tower organic acid such as alkyl mono-carboxylic acid having 2 - 6 C atoms or benzoic acid or their mixture at first temperature range 30 -125°C; passing said organic acid through distillation tower at absence of molecular oxygen; adding to organic acid of first temperature and without molecular oxygen aqueous solution of hydro-halide acid whose temperature is less that said first temperature for preparing aqueous solution of solvent composition at second temperature that is less than first temperature; providing contact of titanium part and solvent composition in distillation tower at absence of molecular oxygen.
EFFECT: possibility for selective removal of iron oxide from surface of titanium parts without damage of said parts.
