ABSTRACT:
Two ferrous-based components are bonded together to form a bonded structure and simultaneously a layer is diffused into the surfaces of the components. The process involves first placing the components in juxtaposition, and contacting the juxtaposed components with a molten lead bath having at least one diffusing element therein. One component may be a corrugated sheet and the other may be an uncorrugated or less corrugated sheet, the sheets being in the form of helixes interposed in each other to create a substantial number of fold lines being in contact with the surface of the uncorrugated sheet. Alternately, a sheet with projections may be used in place of the corrugated sheet.
