The article describes the results of studies on the effect of electrolyte composition and electrochemical operating modes on the resistance of fatigue failure of titanium alloy VT9. Titanium wrought alloy VT9 is characterized by a positive combination of mechanical and technological properties: low density, ductility, high strength, heat resistance, hardenability. The use of this alloy makes it possible to achieve a weight decay of the ware without loss of strength, and, therefore, increase the payload on them. It is noted that in all cases the final machining operations of parts made of titanium alloys including VT9 alloy, subjected to systematic cyclic loads, must be strictly regulated, even better special surface treatment should be provided that removes all adverse surface phenomena and strengthens the metal. After finishing grinding of titanium alloys their resistance to repeated loads is considerably reduced both in low-cycle area and at fatigue test with large number of cycles. Comparative analysis of experimental studies of the endurance limit of samples treated with electrochemical treatment and turning is given. The design and operating principle of the sample processing have been described. It has been stated that after electro-chemical machining on rational regimes, the titanium alloy VT9 possesses sufficient operational properties and is applicable for the manufacture of high resource parts capable of operating at up to 500 ° C.
