Polished Titanium

Background

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

AZoNano - The A to Z of Nanotechnology - 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

AZoNano - The A to Z of Nanotechnology - 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

AZoNano - The A to Z of Nanotechnology - Polished Titanium. 80x80µm image, z-range: 2µm

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.
