Abstract

Workpieces are surface treated by electron bombardment to enhance their mechanical props, by treating the workpiece with a specific number and arrangement of surface members which are relatively closely positioned but are not connected with each other. Changes in grain structure are effected solely with these surface elements by smelting and cooling at a controlled speed. May be used for surface treatment of cast iron workpieces and machine parts.
