Investigation of the influence of Ar pressure on vacuum-arc plasma with Cr-, Cu-, and Zr-cathodes
The work deals with the influence of argon pressure on the ion current of vacuum-arc discharge in the “Bulat-6” setup with Cr-Cu-Zr-cathodes, and also, on the rate of coating deposition on the surfaces being perpendicular and parallel to the plasma stream. It is shown that a substantial decrease in...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | The work deals with the influence of argon pressure on the ion current of vacuum-arc discharge in the “Bulat-6” setup with Cr-Cu-Zr-cathodes, and also, on the rate of coating deposition on the surfaces being perpendicular and parallel to the plasma stream. It is shown that a substantial decrease in both the ion current density and the rate of coating deposition takes place at Ar pressure above 1 Pa. Consideration is given to the elementary processes occurring during plasma stream-gas target interaction. |
