| Abstract: | The present paper has discussed the technologies of Ni-Cr-Al/D.e. composite powder materials used in gas combustion engine for wearable sealing made by solid phase thermo-diffusion process. The influence of co-diffusion of aluminium and chromium, diffusing duration and temperature, active agents, aluminium and chromium raw material powder, etc. on alloying process have been studied. The technological conditions for manufacturing Ni-Cr-Al composite coating powder and the properties of the powder heve been introduced. |
