Titanium is used for implants in human body.
The aim here was to study the morphology, texture and polishing effect of the
surface using atomic force microscopes from NanoSurf.
Raw
Titanium
Figure 1. Raw Titanium. 80x80µm image, z-range: 2µm
The starting surface is irregular and rough.
Due to the processing the surface morphology alters dramatically. The measured
roughness decreases from the top to the bottom.
The roughness of this surface is Rq=0.41µm.
The AFM measurement was done in "Static Force" operating mode.
Anodized
Titanium
Figure 2. Anodized Titanium. 80x80µm image, z-range: 2µm
Anodizing the surface creates a interesting
pattern on the surface.
The roughness of this surface is Rq=0.27µm.
The AFM measurement was done in "Static Force" operating mode.
Polished
Titanium
Figure 3. Polished Titanium. 80x80µm image, z-range: 2µm
The polished surface is the smoothest
surface which is also reflected by the small resulting roughness.
The roughness of this surface is Rq=0.12µm.
The AFM measurement was done in "Dynamic Force" operating
mode. |
