A tool main body to which an insert is attachable, in which the tool main body is made of sintered metal material, and the sintered metal material includes a parent phase made of a metal and a plurality of pores present in the parent phase.

The invention relates to a bone implant, comprising a main body, which has, in its outer region, an open-cell porous lattice structure, which is formed from a plurality of regularly arranged elementary cells, the elementary cells being in the form of an assembled structure and each being composed of an interior and of a plurality of interconnected bars surrounding the interior. The porous lattice structure is provided with a bone-growth-promoting coating comprising calcium phosphate, the calcium phosphate coating having a hydroxylapatite proportion forming a pore inner coating extending into the depth of the porous lattice structure.

Methods and system are provided for a heat exchanger. In one example, a system, comprises a mobile electronic device comprising a front cover and a rear cover, a heat exchanger arranged between the front cover and the rear cover, the heat exchanger comprising a fluid chamber arranged between an inner surface of a first plate and an inner surface of a second plate, and a wick material arranged within the fluid chamber, the wick material comprising a sintered material configured to allow a plurality of fluid passages to extend therethrough.

The present application provides a method for preparing a composite material. The present application provides a method for preparing a composite material comprising a metal porous body and a polymer component, wherein the polymer component is formed in an asymmetrical structure, and a composite material prepared in such a manner.

A heat-exchange pipe that is excellent in heat-exchange property in which a metal porous body is not easily dropped off form a metal pipe; which is provided with the metal pipe and the metal porous body made by joining a plurality of metal fibers bonded to an inner-wall surface of the metal pipe; at least some of the metal fibers in the metal porous body are partially bonded to the inner-wall surface of the metal pipe along a length direction, bended on the inner-wall surface of the metal pipe, and extend to leave from the inner-wall surface.
