In the final machining of hip implants, the polishing process determines the quality of the ultra-smooth surfaces. Polishing for too long exposes hard particles from the material that could later lead to infections and rejections. These particles are captured and quantified by measuring with µsurf. Examination of surface roughness down to the nanometer range ensures that the implants are always of a consistent quality.

Dental implants are roughened by sand blasting and by a subsequent etching process. Roughening means the titanium implant heals into the jaw faster and more durably. The ongoing measurement of the 3D surface roughness during the production process guarantees the manufacturer adherence with the roughness tolerances defined in clinical studies. In the past only qualitative assessment using SEM was available.

Modern vascular implants (stents) are coated with a bioactive layer to prevent regrowth (restinosis). µsurf custom determines both the layer thickness and its homogeneity and the roughness of the surface at the same time. With the µsurf custom, the accuracy of measurements of this type is in the nanometer range. Transparent layers can be captured from 1 µm upwards.

µsurf is an ideal alternative to electron microscopy for many applications in material testing. It excels by virtue of its high-detail reproduction and measurement speed. Time consuming sample preparation is also no longer necessary.
