Nitridation of titanium by laser and plasma mixing technology

Titanium nitride was obtained by the mixing technology with laser and plasma beams nitriding coaxially on the surface of titanium in atmosphere.X-ray diffraction(XRD) measurements reveal formation of titanium nitride in the astreated sample.The more titanium nitride can be obtained by the mixing method than that by the common laser nitriding method.And the oxidation was restrained by the mixing method,too.The relationship of nitriding results with different nitrogen plasma fluxes was discussed.The quantities of titanium nitride increase with the increase of nitrogen plasma fluxes.However,when nitrogen plasma flux is more than 0.8m3/h,the quantities of titanium nitride do not increase anymore.
