Patent

CA 2256207

A casting-die body (1) made of a hardenable copper alloy is provided with an inner wear-protective layer (7) of chromium whose hardness decreases from the billet- side surface (8) in the direction of the casting-die body (1). The wear-protective layer (7) is made up of two chromium layers (9, 10). For this purpose, the casting-die body (1) is given a solution heat treatment, is chromium plated, and is then hardened, as a result of which the initially very high hardness of the chromium layer (9) is reduced. The hardness of the chromium layer (9) then is about 650 HV. Subsequently, to increase the wear protection, the second chromium layer (10) is applied. The result is a conventional chromium-plated layer having a hardness of between 850 HV and 1050 HV.
