doi:10.13251/j.issn.0254-6051.2022.01.033

Abstract

Abstract: Surface nitriding of the Ti-6Al-4V alloy was carried out by vacuum induction rapid nitriding technology, and the specimens before and after nitriding were placed in SBF solution to explore its corrosion resistance. The nitriding layer was characterized by means of Vickers hardness tester, metallographic microscope, electrochemical workstation, optical 3D surface profilometer, scanning electron microscope (SEM) and X-ray diffraction (XRD). The results show that the thickness of nitriding layer in Ti-6Al-4V alloy reaches 20 μm after vacuum induction nitriding treatment at 820 ℃. And the hardness of nitriding layer is obviously improved. Meanwhile, the surface roughness of the sample increases after induction nitriding. Electrochemical tests show that the corrosion resistance of the Ti-6Al-4V titanium alloy is enhanced obviously after induction nitriding.

Key words: Ti-6Al-4V alloy, vacuum induction rapid nitriding, corrosion resistance, SBF solution
