Study on the Micro Removal Process of Inner Surface of Cobalt Chromium Alloy Cardiovascular Stent Tubes

Abstract: Due to the special manufacturing process of cobalt–chromium alloy cardiovascular stent tubes, there are serious surface defects in their inner walls, which affects the therapeutic effect after implantation. At the same time, the traditional processing technology cannot finish the inner wall of a cardiovascular stent tube. In light of the above problems, magnetic abrasive finishing (MAF) equipment for the inner wall of an ultra-fine and ultra-long cardiovascular stent tube is proposed, and MAF technology is use… Show more

“…In the current work, we have investigated the removal of defective layers from the inner walls of cardiovascular stents using magnetic particle finishing, and the magnetic abrasives used were obtained by atomization [ 49 , 50 ]. As reviewed earlier, the disadvantage of the atomization method when preparing magnetic abrasives from expensive hard abrasives such as CBN and PCD is that there is serious waste, and the available grain size does not exceed 50%.…”
