Abstract

The studies results of the structure, chemical and phase composition of the coating formed on the surface of technical VT1-0 titanium after its aluminizing by immersion in the melt are presented. It has been shown that as a result of aluminizing, a continuous coating with a thickness of ~ 15-30 μm without crystallization defects is formed on the titanium surface. At the “coating-titanium” interface there are globular nanosized inclusions with a composition of ~83-84 at. % Al and ~16-17-at. % Ti, corresponding to the TiAl3 intermetalic, which is the richest in aluminum.
