Title:

SACRIFICE CORROSION LAYER FORMING METHOD

Document Type and Number:

WIPO Patent Application WO/2001/029497

Kind Code:

A1

Abstract:

With a mass of sacrifice material (ingot) (Z) placed in a radiator tank main body (234), a radiator tank cap (266), a radiator tube (211), etc. are heat-brazed. This results in the mass of sacrifice material (Z) being heated as it is surrounded by the radiator tank main body (234), so that the sacrifice material evaporated adheres relatively uniformly to the inner wall of the radiator tank main body (234). And the sacrifice material adhering to the inner wall diffuses into the aluminum constituting the radiator tank main body (234) and an alloy layer (sacrifice corrosion layer) containing much sacrifice material is formed on the surface of the inner wall of the radiator tank main body (234).
