In order to fabricate a titanium alloy with superior wear resistance and fatigue strength, fine particle peening (FPP) was introduced as post-treatment after gas blow induction heating (GBIH) nitriding. The surface characteristics of the treated were examined using X-ray diffraction, scanning electron microscopy, laser microscopy micro-Vickers hardness tester. GBIH nitriding FPP formed nitrided...

In order to explore the effect of addition rare earth (RE) a steel microstructure and consequent performance nitrided layer, plasma nitriding was carried out on 38CrMoAl in an atmosphere NH3 at 550 °C for 4, 8, 12 h. The modified layers were characterized using optical microscope (OM), microhardness tester, X-ray diffraction (XRD), scanning electron (SEM), transmission (TEM), electrochemical wo...

The precise control of nitrogen content in high martensitic stainless steel is the guarantee its excellent performance, and a crucial issue for manufacturing process using pressurized gas nitriding. In this paper, effects pressure, temperature alloy composition on solubility nitriding kinetics Fe–Cr–Mo–C melts were investigated. order to correct deviation from Sieverts’ law under first- second-...

In order to improve the low hardness and poor wear resistance of TA2, this paper proposes a composite process cold-rolling low-temperature plasma nitriding with recrystallization. This modification can effectively achieve dual goals modifying matrix structure surface TA2 alloy simultaneously. The experimental results indicate that when deformation rate increases, small-sized grains in sample in...
