METHOD FOR MANUFACTURING A METAL ASSEMBLY HAVING A SHEET OF THERMALLY TREATED ALUMINUM TO OBTAIN ALPHA ALUMINA AND ANOTHER SHEET HAVING SURFACE IRREGULARITIES THAT BECOME EMBEDDED IN SAID SURFACE DURING ROLL BONDING |
摘要 |
A method for manufacturing a metal assembly including an aluminum sheet and at least one metal sheet. An aluminum sheet is treated by heating to a temperature of between 80% and 100% of the melting temperature of the material of which it is comprised for a sufficiently long duration to create and stabilize an alpha alumina layer at the surface of the aluminum sheet. The sheet is then cooled. A metal sheet having a ductility less than or equal to the ductility of the alumimum sheet after cooling is provided, which has surface irregularities having a depth greater than or equal to the thickness of the alpha alumina layer. The aluminum sheet and the metal sheet are roll bonded in a rolling mill to produce the metal assembly, wherein the rolling mill includes at least one cylinder, the outer rolling surface of which is provided with raised portions.
