Corrosion-resistant black marking on surgical steels
Due to the introduction of the UDI standard (unique device identification) in the US and the EU, the medical technology sector is faced with higher requirements when it comes to the traceability of their products. For surgical steels, this means creating clear and legible, as well as corrosion-resistant markings which retain their level of quality in the subsequent clinical daily routine, even after numerous cleaning and disinfection cycles. Due to its physical characteristics, so-called “black marking” using an ultrashort pulse laser is very good suited to creating matt black, corrosion-free markings which retain a consistent level of quality for a particularly long time under clinical conditions. The correct laser parameters are essential for the desired results, and suitable refinishing can achieve further positive effects.
