Development of Trial Manufacturing Process for Co-Cr Alloy Stent with YAG Laser

摘要

This paper deals with a trial manufacturing process for a Co-Cr alloy stent by YAG laser cutting. A fine mesh pattern of the stent is obtained by YAG laser cutting of a metallic thin wall tube. After the laser cutting process, the trial manufacture of a CoCr alloy stent with a high-quality glossy surface is completed by chemical etching for removing an oxide layer on the laser cutting surface and electrolytic polishing serving as a finishing process.
