摘要： A green body for a 3D ceramic and/or metallic body is produced by providing a metal or a mixture of metals and/or a metalloid and/or a non-metal or mixtures thereof in form of at least one aqueous solutions, such as a metal nitrate solution; if more than one aqueous solutions are provided, they differ in composition and/or isotope concentration. One aqueous metal solution is mixed with a gelation fluid at a first temperature to suppress an internal gelation of the feed solution mixture prior to its ejection. The feed solution mixture is ejected by inkjet printing to the green body under construction. The ejected feed solution is heated mixture on the green body to a second temperature to fix it on the green body under construction. Several process steps are repeated according to a 3D production control model until a desired form of the green body is attained.

摘要： Provided is a simple, fast, scalable, and environmentally benign method of producing a graphene-reinforced inorganic matrix composite directly from a graphitic material, the method comprising: (a) mixing multiple particles of a graphitic material and multiple particles of an inorganic solid carrier material to form a mixture in an impacting chamber of an energy impacting apparatus; (b) operating the energy impacting apparatus with a frequency and an intensity for a length of time sufficient for peeling off graphene sheets from the graphitic material and transferring the graphene sheets to surfaces of solid inorganic carrier material particles to produce graphene coated or graphene-embedded inorganic particles inside the impacting chamber; and (c) forming graphene-coated or graphene-embedded inorganic particles into the graphene-reinforced inorganic matrix composite. Also provided is a mass of the graphene-coated or graphene-embedded inorganic particles produced by this method.

摘要： First, in a primary sintering step, a manufacturing system 1 for a sliding member 2 laminates and thereby forms a sintered alloy layer 4 on back metal 3. Subsequently, a large number of indents 5 are formed on a front surface of the sintered alloy layer 4 by an indent-forming mechanism 14. Next, the back metal 3 and sintered alloy layer 4 are rolled by a reduction roll 15 and a secondary sintering process is applied to the sintered alloy layer 4. Consequently, the sliding member 2 is manufactured with the large number of indents 5 provided on a front surface. Since the indents 5 are formed on the sintered alloy layer 4 after the primary sintering step, it is possible to inhibit work hardening from occurring in the indents 5 and surrounding areas.
