Abstract
The article presents studies of transpedicular screws made of titanium alloy BT6. A metallographic and microstructural analysis of screw blanks, prototypes of transpedicular screws made of BT6 alloy and commercially produced screws made of Ti-6Al-4V was performed. Specimens of transpedicular screws were manufactured using the vortex thread cutting method on a CITIZEN Cincom K16E-VII automatic lathe. The microgeometry of the screw surface was created by sandblasting using quartz sand as an abrasive material. Studies have shown that experimental and foreign samples of transpedicular screws have a similar microstructure, consisting of globular crystals of the β-phase located in a light matrix of the α-phase. The microhardness of the rod part of the screw made of Ti-6Al-4V alloy was 312...338 HV, the microhardness of the material of the prototypes was from 264 to 394 HV. Conclusions have been drawn that determine the feasibility of choosing rods made of titanium alloy BT6 as a blank for the manufacture of transpedicular screws.
