Abstract: By coating a workpiece with a uniform layer of polyimide containing surfactant upon the nonweld areas, spatter produced in electron beam welding of the workpiece is prevented from adhering to the workpiece surface in the nonweld areas. The polyimide coating is so constituted as to be adherent, heat stable, acid resistant, and chemically removeable. Silicone surfactant is preferred.

Abstract: Disclosed is apparatus and method for electrochemically finishing the edges of airfoils and other thin edged objects. When the edge on an airfoil varies in thickness along its length, a tapered electrode is provided which has both a decreased diameter and increased spacing distance, providing a means for obtaining an edge with a radius proportioned to the thickness. Generally, in the system having an electrode with a unit surface area A, and with an electrode-workpiece surface spacing distance S, both A and S vary so that the ratio A/S is lowered for electrode portion proximate to edge portions having lowered thickness.
