Abstract

The wide application of titanium alloy parts in the aviation industry and the need to ensure high quality of their manufacture have led to necessity of the developing of new standard samples for determining and controlling the hydrogen content in titanium alloys. In this work the processes of hydrogenation of titanium alloy samples of the VT14 type by etching in a hydrochloric acid solution in the presence of fluorine ions and by electrochemical etching were studied. The material of standard sample blankes of the enterprise with different hydrogen content was manufactured. The hydrogen content in titanium alloys was measured using the emission spectral analysis method with spark excitation of the spectrum.
