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.

摘要： Method for manufacturing steel casts (1 10) intended to obtain a wear element, comprising at least a step of preparing at least a reinforcement insert (1 15), and a step (1 1) of preparing a mold (111) for the cast (1 10) to be manufactured, the step (11) of preparing the mold (11 1) providing a sub-step (14) of positioning the at least one reinforcement insert (1 15) inside the mold (1 1 1) in the zones corresponding to the zones of the cast (1 10) coinciding with those which, in use, will be the zones of the wear element most subjected to wear, and a subsequent step (12) of casting steel inside the mold (111). The step of preparing at least one reinforcement insert (115) provides the operations of filling a substantially filiform tubular container (116) with a mixture of powders and or small pieces (118) and of shaping, also spatially, the filled filiform tubular container (116) to obtain the physical structure of said reinforcement insert (1 15).

摘要： Method for the production of an element subject to wear (10), comprising a metal matrix (14) and at least a core (12) of hard material. The method provides a first step in which a temporary aggregation structure (17) is prepared with at least partly open pores, which volatilize or in any case eliminate at least partly when subjected to heating. A second step in which, on the whole internal and external surface of said temporary aggregation structure ( 17), a liquid mixture of a binder with metal powders which contain hard elements or their precursors is uniformly distributed. A third step in which the temporary aggregation structure (17) is deteriorated by means of a thermal action of controlled heating, so as to take at least part of the temporary aggregation structure (17) to evaporation, rendering free a volume inside the core (12), and to consolidate the mixture according to the conformation of the temporary aggregation structure (17). A fourth step in which the core (12) is disposed in a mold (16) so as to only partly occupy the free volume of the mold (16). A fifth step in which a molten metal material is cast in the mold (16), which metal occupies the free volume and the volume that has been made free, both inside and outside the core (12), so as to anchor to the latter and thus form a single body.

摘要： A method for manufacturing steel casts (110), in particular but not exclusively manganese steel, intended to obtain a wear element, comprises at least a step (15) of making at least a reinforcement insert (115), a step (11) of preparing a mold (111) for the cast (110) to be manufactured, in which the reinforcement insert (115) is positioned, and a subsequent step (12) of casting the steel inside the mold. The reinforcement insert (115) is made by compacting in a desired geometric shape, by means of selective melting techniques, of an amorphous mass of hardening powder (118) obtained by mixing powders of pure elements, or of compounds that form carbides and/or micro-structures of great hardness.
