摘要： A method for producing layered sheet structures from titanium or titanium alloy metal for use in or as electrodes of PEM-type electrolyzers and/or fuel cells comprising the following steps:
a) providing a first sheet-like green part that is formed from a powder of titanium metal, titanium alloy metal and/or titanium hydride and from at least one binder material by selectively positioning material and leaving voids or open spaces therebetween, said first sheet-like green part being a green part of a first metal sheet layer,
or providing a first metal sheet layer comprising a metallic frame structure including voids or open spaces,
b) providing a second sheet-like green part that is formed from a powder of titanium metal, titanium alloy metal and/or titanium hydride and from at least one binder material, said second sheet-like green part being a green part of a second, porous metal sheet layer,
or providing a second metal sheet layer in the form of a porous metal sheet layer,
c) forming a stack comprising
i. the first sheet-like green part and the second sheet-like green part or
ii. the first sheet-like green part and the second metal sheet or
iii. the first metal sheet and the second sheet-like green part,

d) debinding the green part or green parts and sintering the stack to densify the green part or green parts contained therein and to simultaneously bond the metal sheet layers of the stack.

摘要： The present invention relates to a method of manufacturing an aluminum-based clad heat sink and to an aluminum-based clad heat sink manufactured by the method. The method includes (A) a step of preparing a composite powder by ball-milling (i) aluminum or aluminum-alloy powder and (ii) carbon nanotubes (CNT), (B) a step of preparing a multilayer billet including the composite powder, and (C) a step of directly extruding the multilayer billet using an extrusion die to produce a heat sink. The method has an advantage of producing a light high-strength high-conductivity aluminum-based clad heat sink having an competitive advantage in terms of price by using direct extrusion that is suitable for mass production due to its simplicity in process procedure and equipment required.

摘要： A method (800), (900) of making a component (500) of an electric machine using an additive manufacturing process is disclosed. The method includes forming a first lamina (110) of a conductive material (48), building a first layer (113) of a second material (72) on a first surface (102) of the first lamina (110), treating the second material (72) on the first surface (102) of the first lamina (110) to define a first insulative layer (113), and building on the first insulative layer (113) a second lamina (210) of a conductive material (49). The steps can be repeated iteratively until a desired thickness or number of layers is reached.
