Abstract

Molds formed of a zinc aluminum eutectoid, as described on page 1863, are surface-hardened. This is effected by plating a diffusible hardening agent such as copper onto the die surface 10. The plated die is held at an elevated temperature, e.g., 500 degrees F for a period of time, e.g., 30 minutes, causing the plating to diffuse into the surface and produce a surface having enhanced wear resistance.
