    • A composite lay up tool comprising a metal faceplate (12) on a support member (13), wherein the faceplate has been formed by cold-gas dynamic spraying of particles of the metal onto a substrate and wherein the support member is compatible with the faceplate and comprises a casting of a ceramic composition. A process for forming the tool is disclosed. In one aspect, a castable ceramic composition comprises a binder and an aggregate component mixable with water to form a slurry ready for casting, wherein the aggregate component is one of or a mixture of fused silica and a particulate metal alloy, and the binder and aggregate component are present in the proportions 10-50 wt % and 90-50 wt % based on the dry weight of the composition. Also disclosed is a process for producing a faceplate for a lay up tool, which process comprises cold-gas dynamic spraying of particles of a nickel-iron alloy onto a substrate to form a faceplate of the nickel-iron alloy on the substrate, the faceplate being of a thickness in the range 2 to 10 mm. Further disclosed is a process for depositing a metal on a faceplate of a lay up tool in which the faceplate is formed of a nickel-iron alloy, which process comprises preparing an area of a surface of the faceplate to effect cleaning and conditioning of the area to accept and adhere to cold-gas dynamic sprayed particles, and cold-gas dynamic spraying particles of the metal onto the cleaned and conditioned area, wherein the metal is a nickel-iron alloy selected to be compatible with the faceplate.
    • 一种复合铺设工具,其包括在支撑构件(13)上的金属面板(12),其中所述面板已经通过将所述金属颗粒的冷气动态喷涂到基底上形成,并且其中所述支撑构件与所述面板 并且包括陶瓷组合物的铸件。 公开了一种用于形成工具的工艺。 一方面,可浇注陶瓷组合物包含粘合剂和可与水混合以形成准备浇铸的浆料的骨料组分,其中所述聚集体组分是熔融石英和颗粒状金属合金之一或混合物,并且所述粘合剂和聚集体 基于组合物的干重,组分以10-50重量%和90-50重量%的比例存在。 还公开了一种用于生产用于铺设工具的面板的方法,该方法包括将镍 - 铁合金颗粒的冷气动态喷涂到基底上以在基底上形成镍 - 铁合金的面板,面板 厚度在2至10mm的范围内。 进一步公开的是一种用于在铺设工具的面板上沉积金属的方法,其中面板由镍 - 铁合金形成,该方法包括制备面板的表面区域以实现该区域的清洁和调节 接受并粘附到冷气动态喷雾颗粒上,并将金属的冷气动态喷涂颗粒到清洁和调理区域,其中金属是选择为与面板相容的镍 - 铁合金。
