The microstructure observation of the</em><em> sample showed significant porosity as a result of the manufacturing process-(powder technology)</em><em>. The microstructure observation after ultra-sonic treatment revealed that the sample surface was affected by ultra- sonic energy and heterogeneous surface morphologies were observed with slight decrease in porosity due to the deposition of zirconia. </em><em>The hardness results showed that the average value of sample increased from (161.5) HV to (179.5) HV after deposition.&nbsp;&nbsp; </em><em>EDS graph after ultrasonic treatment with zirconia showed the appearance of many elements peaks (Zr,O,C) in addition to Ti peak which indicate that&nbsp; </em><em>the chemical compositions of surfaces was changed &nbsp;on surface</em><em>.</em><em> From AFM measurement ,the surface roughness after zirconia deposition treatment was decrease from (475.43nm) to (272.36) nm</em><em>.</em><em> The deposition of ZrO<sub>2</sub> </em><em>make the nano powder fill the surface porosity</em><em>&nbsp; which leads to&nbsp; reduce surface roughness that creates stable&nbsp; surface and&nbsp; form strong titanium oxide layer which inhabit the ion release.</em></p&gt;}, number={12s}, journal={International Journal of Advanced Science and Technology}, author={Fatima Al-Hassani}, year={2020}, month={May}, pages={1136 - 1143} }
