Effects of Additives on the Surface Layers of Boronized TC4 Titanium Alloys

Abstract:

The boronizing experiments on the surface of Ti-6Al-4V (TC4) titanium alloys were based on solid powder method. Different additives were added into the boronizing agent. The morphologies of surface layers on titanium alloys were observed in scanning electron microscopy (SEM). The phase compositions of boronized layers were analyzed by X-ray diffraction (XRD). The wear resistance properties of boronized TC4 were determined by the friction and wear testing machine. The results showed that all the boronized layers were composed of TiB₂ and TiB dual phases.When 5%Fe₃O₄ was added into the boronizing agent, the boride layer contained more TiB₂ compound and was thicker than those with the addition of 5%Na₂B₄O₇.
