In this paper, Nano composite (HA-ZrO2) was prepared in an effective mechanical mixing method. The calcination and reaction of the powder were done at (1200 °C) for (3 hours). Obtained samples were examined for the wear test of before and after plasma treated at 3 minutes (5, 10 and 15 min.) for the load (10 N.) under constant pressure and rotation number (2950 rive/min.) using a device (Pin on Disc). The Dielectric Barrier Discharge (DBD) Plasma was used under atmospheric pressure to improve the obtained samples. The results showed a significant improvement in hardness values and increased wear coefficient values after the treatment by plasma. That is, the higher the wear and tear coefficient, the more resistant the material will be to the resistance to corrosion and breakdown after plasma treatment.
