Characteristics of Co-Cr alloy L605 tubing for coronary stents;

The Co-W alloy coating was prepared by brush plating at different working voltage, and the microstruc-ture of coating was investigated by means of XRD as well as the bonding strength, oxidation resistance and thermal stability .

The result of stability experiment indicated that the irreversible changes of (BH)max of alloy were 2 to 5 times larger than that of Br and Hc, and the changes of magnetic properties of the Fe-Cr-Co alloy tend to decrease, and then gradually keeps a certain level with increasing the holding time at high temperature.
