Description
Kumail Hussain and seven colleagues coated in 2026 magnesium alloy AZ31 with copper using standard electrode EDM. Magnesium alloys suit temporary implants, but fast corrosion in body fluids limits their use.
Using a Taguchi L9 design, they varied peak current, pulse timing, and gap voltage without added powders, then checked surfaces by microscopy and diffraction and corrosion by polarization tests in saline. The tuned process laid a continuous copper layer about 50 to 60 micrometres thick, smoothing the surface and raising hardness. Corrosion current fell roughly fourfold and corrosion rate dropped about 75 percent, marking plain EDM as a practical route to longer-lived biodegradable implants.
