Study of diffusion oxide hardening on intermetallic materials

Abstract

In the last decade, there has been a tendency to increase the use of titanium ortho-alloys on an intermetallic basis for the manufacture of critical parts. The technology of diffusion oxide hardening on intermetallic materials to increase hardness is proposed. The results of a metallographic study of the structure and phase composition of diffusion oxide hardening are presented. According to the results, the hardness of the VIT-1 intermetallic material in the initial state is 1250 MPa, and with hardening it is 1563 MPa, which is 25% higher than the base material.
