In view of this work, plasma nitriding was executed on Ti-6Al-4V and the effect by using glow discharge with 2 mbar Ar+N2 gas corrosion resistance different time studied. The structure properties external appearance for alloys were performed x-ray diffraction optical microscopic. investigation XRD indicates Ti are polycrystalline a cubic type (bcc). When surface β+α which have been better techn...
