Question

what is "sherardyging"

Answer 1

Sherardizing is the formation of a corrosion-resistant, zinc-iron alloy coating, on the surface of steel or iron. The method involves the heating of the object in an airtight container that has zinc powder. A thermal diffusion process occurs and the zinc diffuses into the object's metal surface, forming the zinc-iron alloy.
