| Abstract: | In the paper, the diffusion of chromium and chromiumnickel into gray cast iron surfaces of pump parts by technique of doubleglow plasma discharge is studied. Under the optimum parameters of technology, the effects of time and temperature on permeated layers of alloying were investigated and the microstructure of the layers permeated by chromium and chromiumnickel alloying and their hardness distribution were analyzed. The results indicates that the permeating technique used for surface hardening of the body and parts of a pump has quite a remarkable effects on reducing their corrosion and increasing economic efficiency. |
