Comparison of the Corrosion Behavior of TiNi Alloys with Martensitic and Austenitic Structures

The work is devoted to the study of the corrosion behavior of TiNi alloys with the original austenitic and martensitic structure in various states. In the course of the research, it was found that the rate of corrosion destruction for coarse-grained and ultrafine-grained Ti49.0Ni51.0 alloys is diffe...

description The work is devoted to the study of the corrosion behavior of TiNi alloys with the original austenitic and martensitic structure in various states. In the course of the research, it was found that the rate of corrosion destruction for coarse-grained and ultrafine-grained Ti49.0Ni51.0 alloys is different: the coarse-grained alloy turned out to be less corrosion resistant and the destruction rate was higher than the corrosion rate in the ultrafine-grained state. X-ray phase analysis of TiNi alloys revealed that as a result of corrosion processes, a change in the phase composition of the alloy occurs, accompanied by the formation of TiNi hydride - TiNiH1.4. In the ultrafine-grained state, the volume fraction of the formed hydride is higher than in the coarse-grained state. This is typical for both alloys, however, in the martensitic alloy, the volume fraction is higher than in the austenitic one.
