Structure of Diffusion Layers on Pure Iron at Powder Borocoppering

Research data for diffusion layers obtained on ARMCO Pure Iron samples in boron- and copper-containing powder mixtures are reported. The aim of this study aim has been to reveal the influence of copper content in a saturating mixture on the structure and thickness of the diffusion layer. In experiments, from 120- to 220-µm-thick diffusion layers with different structures have been obtained on ARMCO Pure Iron samples. It has been found that the thickness of the diffusion layer grows and its structure changes with increasing copper content in the saturating mixture.
