CA 2060952

The resistance to wear-induced failures during forming operations of non-ferrous die tooling materials, such as epoxy-based and zinc-based materials, is improved by treating the surface of the die tooling. In one approach, the surface of an organic-containing or metallic substrate is coated with a silicon-modified organic material and then implanted with ions of an inert gas to transform the organic material to a silicon carbide-rich layer. In the other, nitrogen ions are implanted into the surface of a zinc-based alloy.
