A cermet, as a base, containing a plurality of hard particles and a bonded phase between the plurality of hard particles. Each of the plurality of hard particles, when viewed in cross section, includes a first region containing Ti, N, and C, and contains a titanium carbonitride phase as a main constituent. Each of the plurality of hard particles, when viewed in cross-section, includes a second region containing one or more metal elements selected from the group consisting of V, Nb, Ta, Cr, Mo, W, Co, and Ni in a larger amount than the first region. The content of the one or more metal elements in the second region is 9.5 mass % or more in a total amount. A cutting tool has a length extending from a first end to a second end, and includes a holder and the insert described above.

An additively manufactured (AM) object may include a body including an opening in an exterior surface thereof, the opening having a shape and a first area at the exterior surface of the body. A mask may be positioned over the opening. The mask has the shape of the opening and a second area that is larger than the first area so as to overhang the exterior surface of the body about the opening. A plurality of support ligaments couple to the mask and the exterior surface of the body at a location adjacent to the opening to support a portion of the mask. A coating can be applied to the object, and the mask removed. The final AM object includes a plurality of ligament elements extending from the exterior surface of the body and through the coating adjacent the opening, each ligament element at least partially surrounded by the coating.

A three-dimensional metallic foam is fabricated with an active oxide material for use as an anode for lithium batteries. The porous metal foam, which can be fabricated by a freeze-casting process, is used as the anode current collector of the lithium battery. The porous metal foam can be heat-treated to form an active oxide material to form on the surface of the metal foam. The oxide material acts as the three-dimensional active material that reacts with lithium ions during charging and discharging.
