show the surface roughness profile of bare and n-HA
deposited Ti alloy substrate and the results presented are average of
three experiments. The surface roughness parameters Ra (the arithmetic
mean of the departures of the roughness profile from the mean line),
and Rq (root mean square (RMS) of average roughness) for uncoated Ti
alloy are 2.34 μmand 2.94 μmrespectively. The n-HA coated Ti alloy, exhibited
Ra value of 2.77 μmandtheRq valuewas 3.86 μm. The roughness
of Ti alloy surface increased after coating with n-HA.
