Abstract:
Graphite aluminum composites for use in thermal management applications, such as heat sinks, are manufactured using pressure molds. The materials may be mixed previous to insertion into the mold, or can be mixed within the mold. Further, graphitic particles, such as graphitic needle coke surfaces, can be coated with the aluminum before the mold process is performed. Further, ceramic sheets can be inserted into the mixture before the mold process is performed so that the molded material can then be sliced to provide a carbon aluminum composite plate with a ceramic sheet on one of its surfaces.
Abstract:
Die vorliegende Erfindung stellt einen Aluminium-Matrixverbundwerkstoff bereit, der zur Bildung zumindest eines Reibrings einer Bremsscheibe geeignet ist. Der Aluminium-Matrixverbundwerkstoff weist 20 bis 40 Gew.-% Aluminium, 10 bis 30 Gew.-% Silizium, und gegebenenfalls 2 bis 6 Gew.-% Eisen, 1 bis 3 Gew.-% Nickel, 1 bis 3 Gew.-% Mangan, 1 bis 3 Gew.-% Magnesium, sowie 15 bis 25 Gew.-% Siliziumkarbidpartikel und 15 bis 25 Gew.-% Aluminiumnitridpartikel, bezogen auf ein Gesamtgewicht des Aluminium- Matrixverbundwerkstoffs, auf. Ferner werden ein Verfahren zur Herstellung eines Halbzeugs aus dem Aluminium-Matrixverbundwerkstoff und ein Halbzeug aus dem Aluminium-Matrixverbundwerkstoff offenbart.
Abstract:
This invention relates to a composition of matter comprising predominantly silver metal microribbons, wherein the microribbons are at least 1 micron in length x 0.1 to 0.5 microns in width x 0.05 to 0.5 microns in height. It further relates to a method of making predominantly silver microribbons comprising providing a reducible silver salt, contacting the reducible silver salt with a fogging agent to form latent image silver centers; reducing the reducible silver salt into silver metal using a reducing agent, supplying a polymer that is soluble in a non-aqueous solvent, and a non-aqueous solvent; allowing the growth of the microribbons in the presence of the polymer and non-aqueous solvent
