Study of gas-mixture composition influence on structure and properties of titanium alloy VT6 at low-temperature nitriding

The influence of gas-mixture composition on structure and properties of titanium alloy VT6 (Ti-6Al-4V) at low-temperature nitriding in plasma of non-selfsustained low-pressure arc discharge is studied. The material was in two states: coarse-grained and submicrocrystalline. It is shown that mechanical properties and thickness of the modified layer depend on preliminary formed structure.
