Estimating the term…
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.
A bonded structure comprising at least two adjacent ferrous-based components having a layer diffused in the surface of both of said parts to bond them together, wherein both of said components are sheets of ferrous-based material and at least one of said sheets has spacer means bonded to the other of said sheets to create at least one channel therebetween, said bonded structure being made by the steps of placing said components in juxtaposition, and contacting said juxtaposed components with a molten alloy bath consisting essentially of lead and at least one diffusing element, thereby to create a layer diffused into the surfaces of both of said components which bonds them together.
A bonded structure comprising a corrugated sheet of ferrous-based material having a multiplicity of fold lines, a further sheet of ferrous-based material, said sheets being in the form of helixes interposed in each other such that a substantial number of said fold lines contact a surface of said further sheet, and a layer diffused into the surfaces of both of said sheets so as to bond said corrugated sheet at the lines of contact thereof to said further sheet so as to create a multiplicity of parallel channels.
A bonded structure comprising a first sheet of ferrous-based material having a multiplicity of projections, a second sheet of ferrous-based material, said sheets being in the form of helixes interposed in each other such that a substantial number of said projections contact a surface of said second sheet, and a layer diffused into the surfaces of both of said sheets so as to bond said first sheet at the projections thereof to said second sheet.
A bonded structure comprising a plurality of corrugated sheets of ferrous-based material each having a multiplicity of fold lines, a plurality of further sheets of ferrous-based material, said corrugated sheets alternating with said further sheets such that a substantial number of said fold lines contact a surface of said further sheets, and a layer diffused into the surfaces of all of said sheets so as to bond said corrugated sheets at the fold lines thereof to the adjacent further sheets.
