摘要： A method of creating a texture on at least one surface of a part is disclosed. The part is molded from a feedstock including a powder remaining solid during molding and a binder, and solidified. Then, a physical state of the binder is changed in only a predetermined portion of each surface of the part to be textured. The texture is then created from the predetermined portion by debinding and sintering the part.

摘要： A method of supporting a part (10) with particulate shape retaining media (12) includes placing the part (10) on a bed of the particulate shape retaining media (12), fluidizing the particulate shape retaining media (12) until the part (10) penetrates therein, and vibrating the bed of particulate shape retaining media (12) to compact the particulate shape retaining media (12) around the part (10). The part (10) may be a green part to be debound in a powder injection molding process. Fluidization may be performed through vibrations at a different frequency than the compaction.

摘要： A component (20) including a porous portion (50a) which may be permeable or impermeable to air. The component is a cooled wall segment for a gas turbine engine, including a body defining a contact surface (24) configured to be in contact with circulating hot gas and an outer surface (32) configured to be in contact with cooling air. The body includes a first portion (52a) with at least one retention element, and a porous second portion (50a) made of a porous material permeable to air, containing a plurality of interconnected pores, and having a porosity greater than that of the first portion (52a). The second portion (50a) is engaged to the first portion (52a), defines at least part of the contact surface (24), and defines at least part of a fluid communication between the outer surface (32) and the contact surface (24) through the interconnected pores. The wall segment may be for example a heat shield or shroud segment.

摘要： A process is disclosed for joining two or more powder injection molded parts in which at least two green parts (20,22) are prepared from a feedstock including a binder and an injection powder. The two or more green parts (20,22) are placed into intimate contact, and maintained in intimate contact at a position with a linkage between the at least two green parts (20,22) to produce an interconnected green assembly. The assembly is placed under shape retaining conditions, and the binder of the interconnected green assembly melted under shape retaining conditions to produce a seamless body.
