A method for fabrication of a composite component including a first material containing steel 316L and a second material containing zirconia powder formed in a single sintering. The method for fabrication includes: a) forming a first injection molding composition including steel 316L powder and a second injection molding composition including zirconia powder; b) agglomerating via injection molding one of the first and second compositions to form at least a first part of a blank; c) agglomerating by injection molding the other of the first and second materials against the first part of the blank to form at least a second part of the blank; and d) non-consecutively sintering the first and second compositions forming the blank to obtain the composite component formed of steel 316L and zirconia.

A casting core containing a ceramic and having sufficient mechanical strength to withstand a casting process over a long period of time and good solubility in alkaline solutions. The casting core includes a core, a surface layer, and an intermediate layer between the core and the surface layer. The intermediate layer has a lower relative density than the surface layer and the core.

A bottom face processing method of a pillar-shaped honeycomb structure including steps of: preparing a pillar-shaped honeycomb structure including a plurality of first cells which extend in parallel with each other from a first bottom face to a second bottom face, and each of which is opened in the first bottom face and has a protruding plugged portion in the second bottom face, and a plurality of second cells each of which is adjacent to at least one of the first cells with a partition wall interposed therebetween, which extend in parallel with each other from the first bottom face to the second bottom face, and each of which has a protruding plugged portion in the first bottom face, and is opened in the second bottom face; and removing the protruding portion from the plugged portion of each of the first cells and the second cells of the pillar-shaped honeycomb structure.

Certain exemplary embodiments can provide a method comprising pouring a castable material into a mold to form a dish. The method comprises pressing a first object into the castable material thereby forming a first cavity in the dish. The method comprises pressing a second object into the castable material thereby forming a second cavity in the dish.

A method for machining by laser ablation or by micro-milling a raised and/or hollow structure on an impression of an injection mould. A method for manufacturing a ceramic or cermet item by injection using the injection mould to produce an item, and in particular a watch bezel, decorated directly during the injection.

A method of manufacturing ceramic chips according to one aspect of the present disclosure includes: (A) forming a plurality of dicing trenches on a ceramic wafer; (B) removing a surface in which the dicing trenches are formed by as much as a predetermined thickness to eliminate a rough surface, which is formed on an outer side of each of the dicing trenches when the dicing trenches are formed; and (C) removing a surface opposite to the surface in which the dicing trenches are formed by as much as a predetermined thickness so that the wafer is individualized into a plurality of ceramic chips.

A block has a front face with a first surface of non-planar roughness including at least 10% and not more than 90% of the area of the front face. The front face includes a second surface that is even and generally planar, with at least 10% and not more than 90% of the area of the front face. In one example, the first surface is a split face, and the second surface is a burnished split face. In another example, the first surface is a molded face, and the second surface is burnished. Methods of making a block include molding, curing, in some implementations splitting, and then burnishing. Walls can be constructed from these blocks.

A decorative concrete with a very uniform finish surface and a method of fabricating the same is disclosed. A concrete mixture is poured over a subgrade which defines an exposed surface. The exposed surface is finished with any of several techniques, and the surface is then worked with an abrasive material, and additional techniques are used to color and seal the concrete.
