Beschreibung
Zusammenfassung:	The invention concerns the field of metallurgy, in particular, the metal processing. A method for the chemical treatment of titanium articles consists in etching articles with aqueous solution containing 6-23 % by weight of phosphorus acid and 8.0-9.5 5 be weight of hydrogen peroxide at the temperature of 80-90 DEGREE ?? during 2-6 minutes. Technical result according to this invention is obtaining articles with a low surface darkness.
