The influence nitriding during the combined treatment on the wear resistance of titanium alloy VT22.
Abstract
It was investigated wear resistance of titanium alloy VT22 after combined treatment. The method of combination treatment consisted in previous cold surface plastic deformation (CSPD) and next thermodiffusion nitrogen saturation (TDN) surface, combined with the standard thermal treatment of the alloy. Established that saturation with nitrogen at a temperature 750 °C for 3 h in the second stage standard thermal treatment of alloy causes to a reduction in hardness and improving the quality surface strengthened layer that provides higher tribotechnical characteristics paired with a bronze BrAZhN 10-4-4 compared to saturation for 820 °C 1 h + 750 °C 3 h on the first and second stages of standard thermal treatment of alloy. Dur-ing friction, nitrogen saturation in the second degree of the standard heat treatment alloy VT22 (regime II) in 2 times the in-tensity reduces wear compared to nitrogen saturation of first degree (regime I).References
