Here are the results of research of activity of bioengineering titanic alloys – OT4-1, ВТ-5, BT3-1, BT14, BT16 with different treatment of surface. It is set that most sluggishness in physiological solution (0,9% th NaCl) is characterize α - alloys OT4-1 and BT-5, the surface of which is preliminary polished by a mechanical method with the subsequent anodizing in solution of potassium phosphate. Intermediate poisoning of surface before the receipt of films of oxides of anodes preferably to conduct by boiling in a 10% solution of the calcinated soda. On the alloys of BT3-1 and BT16 the anode oxidizing results in the substantial activating of processes of anodes as compared to mechanically polished.
