    Abstract: A method of forming dense articles from metal or metal alloy powders by friction forming. A self supporting shaped deposit of powder is formed on a substrate. Relative movement is established between the shaped deposit and a friction forming tool. The forming end of the friction tool is urged into compressive contact with the shaped deposit so as to generate an amount of heat sufficient to plasticize the deposit and thereby form a dense article. The steps may be repeated to built up the article to any pre-desired thickness. The substrate may be removed to establish a free standing coherent article, or the article may be left tightly bonded to the substrate. The article is very uniform in both thickness and composition, and enjoys substantially full density and a very fine microstructure.

    Abstract translation: 通过摩擦成形从金属或金属合金粉末形成致密制品的方法。 在基材上形成自支撑成形的粉末沉积物。 在成型沉积物和摩擦成形工具之间建立相对运动。 摩擦工具的成形端被推压成与成形的沉积物压接，从而产生足以塑化沉积物从而形成致密制品的一定量的热量。 可以重复这些步骤以将制品堆积成任何预期的厚度。 可以去除衬底以建立自立的粘合制品，或者制品可以与基底保持紧密结合。 该制品在厚度和组成上都非常均匀，并且具有基本上全密度和非常精细的微观结构。

    Abstract: An end surface 1a of sintered bearing 1 is abutted on a die 10 so that the sintered bearing 1 is mounted thereon, and a tool 40 is abutted on the other end surface 1b of the sintered bearing 1. While the sintered bearing 1 is pressed by the tool 40, high frequency vibration in an axial direction is supplied from a horn 30 to the tool 40 by operating a vibrator 20 so as to give repeated impacts to both end surfaces 1a and 1b of the sintered bearing 1, and pores of the end surfaces 1a and 1b are thereby sealed. The die 10 and the tool 40 have surfaces abutting the sintered bearing 1, and the surfaces have roughness of 0.4 s or less and hardness of HRA 60 or more, and the tool presses the sintered bearing at a pressure of 70 to 700 kPa. The high frequency vibration supplied to the tool 40 has a power of 50 to 3000 W/cm2, and it has a frequency of 10 to 50 kHz.

    Abstract: An apparatus for bonding a particle material to near theoretical density, includes a chamber, a punch and die assembly for supporting a particle material, plungers for applying shear and/or axial pressures, and a power supply for applying a current. In the first stage, a pulsed current of about 1 to 20,000 amps., is applied to the particle material for a predetermined time period, and substantially simultaneously therewith, a shear force of about 5-50 MPa is applied. In the second stage, an axial pressure of about less than 1 to 2,000 MPa is applied to the particle material for a predetermined time period, and substantially simultaneously therewith, a steady current of about 1 to 20,000 amps. is applied. The apparatus may be used to bond metallic, ceramic, intermetallic and composite materials to near-net shape, directly from precursors or elemental particle material without the need for synthesizing the material. The method may also be applied to perform combustion synthesis of a reactive material, followed by consolidation or joining to near-net shaped articles or parts. The apparatus may further be used to repair a damaged or worn substrate or part, coat a particle onto a substrate, and grow single crystals of a particle material.
