Surface Finishing in Medical Technology
Demands on surfaces in the field of medical technology are especially high. Medical instruments must be wear-resistant, corrosion-resistant, and autoclavable. For implants, sterility, surface passivation, and a defined surface structure are additionally required.
Our Solutions for Medical Technology
Surface Property Adjustment
Electropolishing can be performed to achieve specific functional surface properties such as good passivation, low microbial growth rate, and defined roughness in parts.
Coloration, Marking, Oxide Layer Thickening
Color anodization is performed on medical-grade titanium parts to minimize the danger of part mix-up and facilitate part identification during implantation through color-coding and visual marking (with retention of surface functionality).
With "gray anodization," the naturally formed oxide layer is increased in thickness from a few nanometers to 1 to 5 micrometers. This improves the integration behavior of implants and creates the possibility of storing active substances in the layer. The oxide layer also greatly improves the abrasion resistance.
Protective Surface Passivation Layer
Especially in chromium and chromium–nickel stainless steel, the passivation layer forms very slowly in field conditions. Through additional passivation, formation of the protective layer is rapidly completed.
