Method of overlaying stainless steel material for decorative articles and ornaments with a precious metal alloy

摘要

In order to overlay a stainless steel material for decorative articles and ornaments with a precious metal alloy, a comparatively thin layer of said alloy or a plurality of constituent thin layers of said alloy are overlaid on a selected surface of said stainless steel and heated to a temperature higher than 800 DEG C. for the diffusion bonding of said layer or layers to the stainless body and for annealing of said body, and thereafter another thicker layer or constituent layers of a precious metal alloy are overlaid on the stainless steel material with or without heating said second-mentioned layer or layers.
