Development and assimilation of an electron-beam deposition process for strengthening and restoration of metallurgical-equipment components

The Institute of Strength Physics and Materials Science (Siberian Department, Russian Academy of Sciences) has developed a process for electron-beam deposition of powdered composite materials on metallurgically-produced parts. A unique electron-beam deposition device, the LUNa-10, for reinforcement of blower nozzles used in blast-furnace casting and for reinforcement of crystallizers in continuous steel casting machines was developed and placed into service at the West Siberian Metallurgical Combine (Novokuznetsk). This paper describes some characteristics of the electron-beam deposition process for composite coatings, and the properties of such coatings as a function of composition and purpose.
