Development of hardening technology for working surfaces of microsurgical instruments made of titanium alloy

Abstract

The structure and properties of materials and working surfaces of needle holders were studied to improve the technology of their manufacture according to the characteristics of hardness and functionality of a microsurgical instrument. The types and modes of volumetric and surface hardening of VT6 titanium alloy (Ti-6Al-4V) using laser technologies adapted to the working surfaces of the tool are proposed. The possibility of using the alloy to replace maraging steel in the manufacture of needle holders is evaluated
