An exemplary process includes determining a desired pore size, selecting an initial pore size greater than the target pore size, manufacturing a porous structure with the initial pore size, forging the porous structure to form a forged part having the desired pore size, and forming an orthopedic device from the forged part.

A ceramic and plastic composite and a method for fabricating the same are disclosed. A chemical cleaning treatment, a microetching treatment, a hole reaming treatment, and a surface activating treatment are performed on the surface of a ceramic matrix to form nanoholes with an average diameter ranging between 150 nm and 450 nm. Plastics are injected onto the surface of the baked ceramic matrix to form a plastic layer. The plastic layer more deeply fills the nanoholes to have higher adhesion. Thus, the higher combined strength and air tightness exist between the ceramic matrix and the plastic layer to improve the reliability and the using performance of the ceramic and plastic composite.

Provided is a method for producing a composite member formed by bonding a base material and a resin member. The method includes: a surface treatment step of forming micro-order or nano-order asperities on a surface of a base material; and a bonding step of directly bonding, by injection molding, a resin member to the surface of the base material that has the asperities formed in the surface treatment step. In addition, the composite member includes: a base material having micro-order or nano-order asperities on a surface thereof; and a resin member that is in direct contact with the surface of the base material.

The invention also relates to Plastic-metal hybrid part, obtainable by said process, wherein a metal part is overmolded by a polyamide composition comprising a blend of a semi-crystalline semi-aromatic polyamide and an amorphous semi-aromatic polyamide.

The present invention relates to a method for producing a two-dimensional composite component (150) having a porous basic component (152) and an injection molded component (154) rigidly joined to the basic component (152), said method comprising the following steps: introduction of the mat-like or panel-like basic component (152), comprising two mutually spaced-apart base sides (152b1, 152b2) and a circumferential narrow side (152s) joining the base sides (152b1, 152b2), into a basic component cavity (114) of a molding tool (112), which further comprises an injection molding cavity (116), closure of the molding tool (112), so that at least a portion (152s) of the basic component (152) forms a portion of a wall of the injection molding cavity (116), and injection of injection molding material (156) into the injection molding cavity (116), and formation thereby of the injection molding component (154) and joining of the injection molding component (154) to the basic component (152), wherein upon closure of the molding tool (112) before the injection molding material (156) is injected, the entire region (152s), formed by the basic component (152), of the wall of the injection molding cavity (116) is formed by the narrow side (152s) of the basic component (152).

A stainless steel and synthetic resin composite molded body and preparation method thereof. After the surface of the flat and even stainless steel had anchor effect, it was connected with various synthetic resin pieces by means of insertion molding. Regardless of the material of the stainless steel pi ece, the indenting test proved that the strength, of over 15 N/mm.sup.2 after connection enabled stable tightness. With insertion molding of the stainless steel piece having anchor effect in the present invention, composite molded products comprising various resin parts can be produced if no displacement or height difference occurs.

The present disclosure provides a metal-resin composite and a preparation method. The metal-resin composite includes a metal substrate; a porous resin layer formed on the metal substrate; a plastic layer formed on the porous resin layer; and a pore passage. The pore passage passes through the porous resin layer and extends inside the metal substrate, and the plastic layer fills in the pore passage to bond with the metal substrate.
