    • The present invention is directed to a method for the production of highly demanded pieces at low cost. The method is especially well suited for deep drawing dies, but also any other type of tooling. It is also very well suited for machine components of big dimensions and with high mechanical solicitations, like rotors and cages in wind mills and other big machines. The pieces or tools are cast with a low cost ceramic, like a high resistance concrete (with special mention to HPC or UHPC) or a low water admixture castable or any other low cost high mechanical resistance material (low cost ceramics or high resistance polymers are especially suited). Once cast, the working surface of the die or piece is coated with a metal, an intermetallic or a high performance ceramic. Projection or deposition techniques are used to obtain the high value working surface. Optionally localized fusion treatments (IR, laser,HDIR or any other localized energy source) are applied to obtain full density on the surface. Also welding, laser deposition or any other deposition by melting can be applied (often on top of a deposited or projected intermediate layer). Different layers can be applied, and trough proper masking a specific surface functionality can be attained. Rolls, jaws, bearing supports, machine benches and other structural parts and any other highly solicited part can be obtained at low cost by means of the present invention.
    • 本发明涉及一种低成本生产高要求件的方法。 该方法特别适用于深拉模,也可适用于任何其他类型的模具。 它也非常适用于大尺寸的机器部件,并具有高机械性能,如风车和其他大型机器中的转子和保持架。 这些零件或工具用低成本陶瓷铸造,如高阻混凝土(特别提及HPC或UHPC)或低水混合浇注料或任何其他低成本高机械电阻材料(低成本陶瓷或高电阻聚合物 特别适合)。 一旦铸造,模具或件的工作表面涂覆有金属,金属间或高性能陶瓷。 使用投影或沉积技术来获得高价值的工作表面。 任选局部融合处理(IR,激光,HDIR或任何其他局部能量源)被应用以获得表面上的全密度。 还可以施加焊接,激光沉积或通过熔化的任何其它沉积(通常在沉积或投影的中间层的顶部)。 可以应用不同的层,并且可以实现适当掩蔽特定的表面功能。 可以通过本发明以低成本获得辊,颚,轴承座,机台和其他结构部件以及任何其它高度要求的部件。
