Conclusions
A study was made of the processes of diffusion impregnation of refractory metals in powder mixtures with 1–30 wt.% copper additions. It was found that the addition of up to 5 wt.% copper to the mixture accelerated the process of boronizing of refractory metals. The presence of more than 10 wt.% copper in the siliconizing mixture adversely affected the quality of the suicide coating. The addition of copper to the impregnating mixtures enabled good-quality diffusion coatings of considerable thickness to be obtained.
