A method and apparatus for improving the integrity of metal plated composites is disclosed. Plating improvements are achieved by first irradiating a nickel plated substrate, prior to application of a noble metal plating layer, to smooth any surface discontinuities or irregularities. Excimer laser pulses, having a duration of less than 100 nanoseconds, are employed to partially liquefy the upper surface of the nickel plating on the substrate. This invention is compatible with conventional plating processes, such as electroplating.read more

Laser polishing of medical devices
TL;DR: In this article, a desired portion of a stent may be polished by irradiating at least a portion of the surface of the stent substrate with a laser beam from the laser at a wavelength absorbed by the substrate to cause a controlled level of melting, allowing the substrate material to solidify.
