Examination of Copper or Nickel Coats on W-Base Composites

Abstract

Tungsten-base composites coated with either nickel or copper were heat treated at elevated temperatures to produce a diffusion bond between the composite and the coat. At temperatures to 473 K, no diffusion bond was achieved and there was no improvement in low-temperature ductility. At temperatures above 920 K, the coat and base bonded and the ductility was improved. Microprobe analysis confirmed that a diffusion bond formed.
