Fremgangsmåde til fremstilling af et element, der er udsat for slid, og et således opnået element, der er udsat for slid

摘要

Method to produce an element (10) subject to wear, such as a mechanical member, an abrasion or crushing tool or suchlike, comprising a metal matrix (14) and at least a core (12) of ceramic material. The method comprises a preliminary step wherein the core (12) is prepared by mixing at least a first component with a base of aluminum oxide in the form of a (a-Al2O3) with a second component comprising a eutectic compound with a base of a-Al2O3 and ZrO2, a second step wherein the core (12) is arranged in a mold, so as to define a free volume inside the mold, and a third step wherein a molten metal material is cast into the mold, to occupy the free volume so as to anchor to the core (12) and thus form a single body.
