ABSTRACT:
Disclosed is an electron beam drilling process in which the workpiece surface first penetrated by the beam is coated with a stop-off material having the required high temperature resistance for preventing formation of burrs around the perimeter of the hole from hot molten spatter which is ejected from the entrance to the hole during the drilling operation. A preferred stop-off material is a substantially continuous layer of boron nitride on the first penetrated surface of the workpiece.
